What does 1 John 4:9 Mean?

Study Notes

world
kosmos = mankind.
The Greek word kosmos means "order," "arrangement," and so, with the Greeks, "beauty"; for order and arrangement in the sense of system are at the bottom of the Greek conception of beauty.
When used in the N.T. of humanity, the "world" of men, it is organized humanity-- humanity in families, tribes, nations--which is meant. The word for chaotic, unorganized humanity--the mere mass of man is thalassa, the "sea" of men (e.g.) Revelation 13:1 (See Scofield " Revelation 13:8 ") . For "world" (kosmos) in the bad ethical sense, "world system" John 7:7 .

Verse Meaning

The proof of God"s love for people is that He sent His only begotten Son (lit. only born one) to provide eternal life for us (cf. John 1:14; John 1:18; John 3:16). [1]

Context Summary

1 John 4:1-11 - The Token Of God's Love
In those days the intense ferment of men's minds wrought many delusions and heresies which were fraught with temptation to young converts, and the Apostle wished to give tests for determining which voice spake from God. The confession of Jesus Christ as the Incarnate Word, a spirit of love and gentleness, and the willingness to abide in the doctrine of the Apostles, were signs that the speaker was commissioned by Christ.
Wouldst thou overcome the world? Let Christ enter, and the world will have no charms for thee. There is only one source of pure, divine love, and wherever that love is present, you know that the possessor has found its source in God. God's love is absolutely selfless. He loves the unloving to make them love, putting away their sin and perfecting their union with Himself. [source]

John 3:15 Have eternal life []
A characteristic phrase of John for live forever. See John 3:16, John 3:36; John 5:24; John 6:40, John 6:47, John 6:54; 1 John 3:15; 1 John 5:12. The interview with Nicodemus closes with John 3:15; and the succeeding words are John's. This appears from the following facts: 1. The past tenses loved and gave, in John 3:16, better suit the later point of view from which John writes, after the atoning death of Christ was an accomplished historic fact, than the drift of the present discourse of Jesus before the full revelation of that work. 2. It is in John's manner to throw in explanatory comments of his own (John 1:16-18; John 12:37-41), and to do so abruptly. See John 1:15, John 1:16, and on and, John 1:16. 3. John 3:19is in the same line of thought with John 1:9-11in the Prologue; and the tone of that verse is historic, carrying the sense of past rejection, as loved darkness; were evil. 4. The phrase believe on the name is not used elsewhere by our Lord, but by John (John 1:12; John 2:23; 1 John 5:13). 5. The phrase only-begotten son is not elsewhere used by Jesus of himself, but in every case by the Evangelist (John 1:14, John 1:18; 1 John 4:9). 6. The phrase to do truth (John 3:21) occurs elsewhere only in 1 John 1:6. -DIVIDER-

John 21:1 Shewed [ἐφανέρωσεν]
This rendering might easily convey merely the sense of appearing; but its meaning is much deeper. Occurring frequently in the New Testament, it is used most frequently of God and Christ, or of men in their relation to these. Thus, of Christ in person while upon earth (Mark 16:12, Mark 16:14; John 1:31; John 2:11; 1 Peter 1:20; 1 John 1:2). Of the works of Christ (John 2:11; John 9:3; 1 John 3:5). Of Christ in redemption (1 John 3:5). Of Christ in His second coming (1 John 2:28). Of Christ in glory (1 John 3:2; Colossians 3:4). It is used of God. Of His revelation to men of the knowledge of Himself (Romans 1:19). Of His manifestation in Christ (1 Timothy 3:16). Of His righteousness (Romans 3:21). Of His love (1 John 4:9). It is used of men. As epistles manifesting the character and spirit of Christ (2 Corinthians 3:3; 2 Corinthians 5:11). In the judgment (2 Corinthians 5:10). In all these cases the appearing is not merely an appeal to sense, but is addressed to spiritual perception, and contemplates a moral and spiritual effect. It is the setting forth of the law or will or character of God; of the person or work of Christ; of the character or deeds of men, with a view to the disclosure of their quality and to the producing of a moral impression. Rev., manifested. [source]
John 16:30 By this [ἐν τούτῳ]
Literally, in this. Compare 1 John 2:3, 1 John 2:5; 1 John 3:16, 1 John 3:19, 1 John 3:24; 1 John 4:9, 1 John 4:10, 1 John 4:13, 1 John 4:17; 1 John 5:2. [source]
John 5:42 But I know you [αλλα εγνωκα υμας]
Perfect active indicative of γινωσκω — ginōskō “I have come to know and still know,” the knowledge of personal experience (John 2:24.). The love o‘ God Objective genitive, “the love toward God.” See Luke 11:42 for this phrase in the same sense (only other instance in the Gospels, but common in 1John (1 John 2:5; 1 John 3:17; 1 John 4:7, 1 John 4:9; 1 John 5:3) and in 2 Thessalonians 3:5; 2 Corinthians 13:14; Romans 5:5. The sense of God‘s love for man occurs in 1 John 3:1; 1 John 4:9, 1 John 4:10, 1 John 4:16; John 15:9. of Christ‘s love for man. These rabbis did not love God and hence did not love Christ. [source]
John 1:14 And the Word became flesh [και ο λογος σαρχ εγενετο]
See John 1:3 for this verb and note its use for the historic event of the Incarnation rather than ην — ēn of John 1:1. Note also the absence of the article with the predicate substantive σαρχ — sarx so that it cannot mean “the flesh became the Word.” The Pre-existence of the Logos has already been plainly stated and argued. John does not here say that the Logos entered into a man or dwelt in a man or filled a man. One is at liberty to see an allusion to the birth narratives in Matthew 1:16-25; Luke 1:28-38, if he wishes, since John clearly had the Synoptics before him and chiefly supplemented them in his narrative. In fact, one is also at liberty to ask what intelligent meaning can one give to John‘s language here apart from the Virgin Birth? What ordinary mother or father ever speaks of a child “becoming flesh”? For the Incarnation see also 2 Corinthians 8:9; Galatians 4:4; Romans 1:3; Romans 8:3; Philemon 2:7.; 1 Timothy 3:16; Hebrews 2:14. “To explain the exact significance of εγενετο — egeneto in this sentence is beyond the powers of any interpreter” (Bernard). Unless, indeed, as seems plain, John is referring to the Virgin Birth as recorded in Matthew and Luke. “The Logos of philosophy is, John declares, the Jesus of history” (Bernard). Thus John asserts the deity and the real humanity of Christ. He answers the Docetic Gnostics who denied his humanity. Dwelt among us First aorist ingressive aorist active indicative of σκηνοω — skēnoō old verb, to pitch one‘s tent or tabernacle First aorist middle indicative of τεαομαι — theaomai (from τεα — thea spectacle). The personal experience of John and of others who did recognize Jesus as the Shekinah glory John employs τεαομαι — theaomai again in John 1:32 (the Baptist beholding the Spirit coming down as a dove) and John 1:38 of the Baptist gazing in rapture at Jesus. So also John 4:35; John 11:45; 1 John 1:1.; 1 John 4:12, 1 John 4:14. By this word John insists that in the human Jesus he beheld the Shekinah glory of God who was and is the Logos who existed before with God. By this plural John speaks for himself and all those who saw in Jesus what he did. As of the only begotten from the Father Strictly, “as of an only born from a father,” since there is no article with μονογενους — monogenous or with πατρος — patros In John 3:16; 1 John 4:9 we have τον μονογενη — ton monogenē referring to Christ. This is the first use in the Gospel of πατηρ — patēr of God in relation to the Logos. Μονογενης — Monogenēs (only born rather than only begotten) here refers to the eternal relationship of the Logos (as in John 1:18) rather than to the Incarnation. It distinguishes thus between the Logos and the believers as children John clearly means to say that “the manifested glory of the Word was as it were the glory of the Eternal Father shared with His only Son” (Bernard). Cf. John 8:54; John 14:9; John 17:5. Full Probably indeclinable accusative adjective agreeing with δοχαν — doxan (or genitive with μονογενους — monogenous) of which we have papyri examples (Robertson, Grammar, p. 275). As nominative πληρης — plērēs can agree with the subject of εσκηνωσεν — eskēnōsen Of grace and truth Curiously this great word χαρις — charis (grace), so common with Paul, does not occur in John‘s Gospel save in John 1:14, John 1:16, John 1:17, though αλητεια — alētheia (truth) is one of the keywords in the Fourth Gospel and in 1John, occurring 25 times in the Gospel and 20 in the Johannine Epistles, 7 times in the Synoptics and not at all in Revelation (Bernard). In John 1:17 these two words picture the Gospel in Christ in contrast with the law of Moses. See Epistles of Paul for origin and use of both words. [source]
John 3:15 That whosoever believeth may in him have eternal life [ινα πας ο πιστευων εν αυτωι εχηι ζωην αιωνιον]
Final use of ινα — hina with present active subjunctive of εχω — echō that he may keep on having eternal life (a frequent phrase in John, always in John αιωνιος — aiōnios occurs with ζωη — zōē 16 times in the Gospel, 6 in 1John, ageless or endless life, beginning now and lasting forever). It is more than endless, for it is sharing in the life of God in Christ (John 5:26; John 17:3; 1 John 5:12). So here εν αυτωι — en autōi (in him) is taken with εχηι — echēi rather than with πιστευων — pisteuōn The interview with Nicodemus apparently closes with John 3:15. In John 3:16-21 we have past tenses constantly as is natural for the reflection of John, but unnatural for Jesus speaking. There are phrases like the Prologue (John 3:19; John 1:9-11). “Only begotten” does not occur elsewhere in the words of Jesus, but is in John 1:14, John 1:18; 1 John 4:9. John often puts in explanatory comments (John 1:16-18; John 12:37-41). [source]
John 6:57 The living Father [ο ζων πατηρ]
Nowhere else in the N.T., but see John 5:26 and “the living God” (Matthew 16:16; 2 Corinthians 6:16). The Father is the source of life and so “I live because of the Father” He that eateth me Still bolder putting of the mystical appropriation of Christ (John 6:51, John 6:53, John 6:54, John 6:56). Because of me The same idea appears in John 14:19: “Because I live ye shall live also.” See John 11:25. Jesus Christ is our ground of hope and guarantee of immortality. Life is in Christ. There is no real difficulty in this use of δια — dia with the accusative as with δια τον πατερα — dia ton patera just before. It occurs also in John 15:3. As the Father is the fount of life to Christ, so Christ is the fount of life to us. See 1 John 4:9 where δια — dia is used with the genitive (δι αυτου — di' autou) as the intermediate agent, not the ground or reason as here. [source]
Hebrews 12:9 And live [καὶ ζήσομεν]
Have true life; not limited to the future life. Comp. John 5:26; John 6:57; 1 John 5:11; Revelation 11:11; Acts 16:28; Romans 6:11; Romans 14:8; 1 John 4:9, and see on living God, Hebrews 3:12. [source]
Hebrews 1:6 The first-begotten [τὸν πρωτότοκον]
Mostly in Paul and Hebrews. Comp. Romans 8:29; Colossians 1:15, Colossians 1:18; Revelation 1:5. Μονογενής only-begotten(John 1:14, John 1:18; John 3:16, John 3:18; 1 John 4:9, never by Paul) describes the unique relation of the Son to the Father in his divine nature: πρωτότοκος first-begottendescribes the relation of the risen Christ in his glorified humanity to man. The comparison implied in the word is not limited to angels. He is the first-born in relation to the creation, the dead, the new manhood, etc. See Colossians 1:15, Colossians 1:18. The rabbinical writers applied the title first-born even to God. Philo (De Confus. Ling. § 14) speaks of the Logos as πρωτόγονος or πρεσβύτατος thefirst-born or eldest son. [source]
1 John 5:4 That overcometh [ἡ νικήσασα]
The aorist tense, overcame. On the cumulative form of expression, the victory, that which overcame, see on 1 John 4:9. The aorist is to be held here to its strict sense. The victory over the world was, potentially, won when we believed in Jesus as the Christ, the Son of God. We overcome the world by being brought into union with Christ. On becoming as He is (1 John 3:17) we become partakers of His victory (John 16:33). “Greater is He that is in you than He that is in the world” (1 John 4:4). [source]
1 John 4:14 Sent []
See on 1 John 4:9. [source]
1 John 2:5 Is the love of God perfected [ἡ ἀγάπη τοῦ Θεοῦ τετελείωται]
Rev., rendering the perfect tense more closely, hath the love of God been perfected. The change in the form of this antithetic clause is striking. He who claims to know God, yet lives in disobedience, is a liar. We should expect as an offset to this: He that keepeth His commandments is of the truth; or, the truth is in him. Instead we have, “In him has the love of God been perfected.” In other words, the obedient child of God is characterized, not by any representative trait or quality of his own personality, but merely as the subject of the work of divine love: as the sphere in which that love accomplishes its perfect work. The phrase ἡ ἀγάπη τοῦ Θεοῦ the love of God, may mean either the love which God shows, or the love of which God is the object, or the love which is characteristic of God whether manifested by Himself or by His obedient child through His Spirit. John's usage is not decisive like Paul's, according to which the love of God habitually means the love which proceeds from and is manifested by God. The exact phrase, the love of God or the love of the Father, is found in 1 John 3:16; 1 John 4:9, in the undoubted sense of the love of God to men. The same sense is intended in 1 John 3:1, 1 John 3:9, 1 John 3:16, though differently expressed. The sense is doubtful in 1 John 2:5; 1 John 3:17; 1 John 4:12. Men's love to God is clearly meant in 1 John 2:15; 1 John 5:3. The phrase occurs only twice in the Gospels (Luke 6:42; John 5:42), and in both cases the sense is doubtful. Some, as Ebrard, combine the two, and explain the love of God as the mutual relation of love between God and men. It is not possible to settle the point decisively, but I incline to the view that the fundamental idea of the love of God as expounded by John is the love which God has made known and which answers to His nature. In favor of this is the general usage of ἀγάπη lovein the New Testament, with the subjective genitive. The object is more commonly expressed by εἰς towardsor to. See 1 Thessalonians 3:12; Colossians 1:4; 1 Peter 4:8. Still stronger is John's treatment of the subject in ch. 4. Here we have, 1 John 4:9, the manifestation of the love of God in us ( ἐν ἡμῖν ) By our life in Christ and our love to God we are a manifestation of God's love. Directly following this is a definition of the essential nature of love. “In this is love; i.e., herein consists love: not that we have loved God, but that He loved us ” (1 John 4:10). Our mutual love is a proof that God dwells in us. God dwelling in us, His love is perfected in us (1 John 4:12). The latter clause, it would seem, must be explained according to 1 John 4:10. Then (1 John 4:16), “We have known and believed the love that God hath in us ” (see on John 16:22, on the phrase have love ). “God is love;” that is His nature, and He imparts this nature to be the sphere in which His children dwell. “He that dwelleth in love dwelleth in God.” Finally, our love is engendered by His love to us. “We love Him because He first loved us” (1 John 4:19). -DIVIDER-
-DIVIDER-
In harmony with this is John 15:9. “As the Father loved me, I also loved you. Continue ye in my love.” My love must be explained by I loved you. This is the same idea of divine love as the sphere or element of renewed being; and this idea is placed, as in the passage we are considering, in direct connection with the keeping of the divine commandments. “If ye keep my commandments ye shall abide in my love.”-DIVIDER-
This interpretation does not exclude man's love to God. On the contrary, it includes it. The love which God has, is revealed as the love of God in the love of His children towards Him, no less than in His manifestations of love to them. The idea of divine love is thus complex. Love, in its very essence, is reciprocal. Its perfect ideal requires two parties. It is not enough to tell us, as a bare, abstract truth, that God is love. The truth must be rounded and filled out for us by the appreciable exertion of divine love upon an object, and by the response of the object. The love of God is perfected or completed by the perfect establishment of the relation of love between God and man. When man loves perfectly, his love is the love of God shed abroad in his heart. His love owes both its origin and its nature to the love of God. -DIVIDER-
-DIVIDER-
The word verily ( ἀληθῶς ) is never used by John as a mere formula of affirmation, but has the meaning of a qualitative adverb, expressing not merely the actual existence of a thing, but its existence in a manner most absolutely corresponding to ἀλήθεια truthCompare John 1:48; John 8:31. Hath been perfected. John is presenting the ideal of life in God. “This is the love of God that we keep His commandments.” Therefore whosoever keepeth God's word, His message in its entirety, realizes the perfect relation of love.

1 John 1:7 Of Jesus Christ His Son []
Omit Christ. The human name, Jesus, shows that His blood is available for man. The divine name, His Son, shows that it is efficacious. I shall be rendering a service to students of John's Epistles by giving, in a condensed form, Canon Westcott's note, classifying the several names of our Lord and their uses in the Epistles. The name in John, as in the Bible elsewhere, has two distinct, but closely connected meanings. -DIVIDER-

1. The Revelation of the Divine Being by a special title. -DIVIDER-
-DIVIDER-
2. The whole sum of the manifold revelations gathered up so as to form one supreme revelation. -DIVIDER-

The latter sense is illustrated in 3 John 1:7, where “the name” absolutely includes the essential elements of the Christian creed, the complete revelation of Christ's work in relation to God and man. Compare John 20:31; Acts 5:41. -DIVIDER-
-DIVIDER-
In 1 John 2:12, the term is more limited, referring to Christ as He lived on earth and gave Himself for “the brethren.” In 1 John 3:23; 1 John 5:13, the exact sense is defined by what follows. -DIVIDER-

(I.) His Son Jesus Christ. 1 John 1:3; 1 John 3:23; 1 John 5:20. The divine antecedent is differently described in each case, and the difference colors the phrase. In 1 John 1:2-3, the Father (compare 1John href="/desk/?q=1jo+3:23&sr=1">1 John 3:23, God. In 1 John 5:20, He that is true. Thus the sonship of Christ is regarded in relation to God as Father, as God, and as satisfying the divine ideal which man is able to form.

The expression, the blood of Jesus His Son, is chosen with a profound insight. Though Ignatius uses the phrase blood of God yet the word blood is inappropriate to the Son conceived in His divine nature. The word Jesus brings out His human nature, in which He assumed a real body of flesh and blood, which blood was shed for us.Cleanseth ( καθαρίζει )See on Mark 7:19. Not only forgives but removes. Compare Titus 2:14; Hebrews 9:13sq.; Hebrews 9:22sq.; Ephesians 5:26sq.; Matthew 5:8; 1 John 3:3. Compare also 1 John 1:9, where, forgive ( ἀφῇ ) and cleanse ( καθαρίσῃ ) occur, with an obvious difference of meaning. Note the present tense cleanseth. The cleansing is present and continuous. Alexander (Bishop of Derry) cites a striking passage from Victor Hugo (“Le Parricide”). The usurper Canute, who has had a share in his father's death, expiring after a virtuous and glorious reign, walks towards the light of heaven. But first he cuts with his sword a shroud of snow from the top of Mt. Savo. As he advances towards heaven, a cloud forms, and drop by drop his shroud is soaked with a rain of blood.All sin ( πάσης ἁμαρτίας )The principle of sin in all its forms and manifestations; not the separate manifestations. Compare all joy (James 1:2); all patience (2 Corinthians 7:12); all wisdom (Ephesians 1:8); all diligence (2 Peter 1:5). [source]

1 John 1:2 That eternal life [τὴν ζωὴν τὴν αἰώνιον]
A particularly faulty translation, since it utterly fails to express the development of the idea of life, which is distinctly contemplated by the original. Render, as Rev., the life, the eternal life; or the life, even the eternal life. For a similar repetition of the article compare 1 John 2:8; 1 John 4:9; 2 John 1:11. This particular phrase occurs only here and John 2:25. John uses ζωὴ αἰώνιος eternallife, and ἡ αἰώνιος ζωη the eternal life, the former expressing the general conception of life eternal, and the latter eternal life as the special gift of Christ. Αἰώνιος eternaldescribes the life in its quality of not being measured by time, a larger idea than that of mere duration. [source]
1 John 4:14 Hath sent [απεσταλκεν]
As in 1 John 4:9, though απεστειλεν — apesteilen in 1 John 4:10.To be the Saviour of the world (σωτηρα του κοσμου — sōtēra tou kosmou). Predicate accusative of σωτηρ — sōtēr (Saviour), like ιλασμον — hilasmon in 1 John 4:10. This very phrase occurs elsewhere only in John 4:42 as the confession of the Samaritans, but the idea is in John 3:17. [source]
1 John 5:3 This [αυτη]
Explanatory use of ινα — hina with αυτη — hautē as in John 17:3, to show what “the love of God” (1 John 4:9, 1 John 4:12) in the objective sense is, not mere declamatory boasting (1 John 4:20), but obedience to God‘s commands, “that we keep on keeping (present active subjunctive as in 1 John 2:3) his commandments.” This is the supreme test. [source]
2 John 1:2 Which dwelleth [τὴν μένουσαν]
Rev., abideth. Enlarging on the idea of the truth: that which abideth. See on 1 John 4:9, on the phrase to abide in, see on 1 John 2:6. [source]
Revelation 6:17 The great day [ἡ ἡμέρα ἡ μεγάλη]
Lit., the day, the great (day ). For the construction, see on 1 John 4:9. [source]
Revelation 2:28 The morning-star [τὸν ἀστέρα τὸν πρωΐ́νόν]
The star, that of the morning. One of John's characteristic constructions. See on 1 John 4:9. The reference is, most probably, to Christ himself. See Revelation 22:16. He will give Himself. This interpretation falls in with the promise of power over the nations in Revelation 2:26. The star was the ancient emblem of sovereignty. See Numbers 24:17; Matthew 2:2. “It was the symbol of sovereignty on its brighter and benignant side, and was therefore the fitting and necessary complement of the dread attributes that had gone before. The king came not only to judge and punish, but also to illumine and cheer” (Plumptre). Compare 2 Peter 1:19. [source]
Revelation 12:9 That old serpent [ὁ ὄφις ὁ ἀρχαῖος]
Lit., the serpent, the old (serpent). For this habitual construction in John, see on 1 John 4:9. For ἀρχαῖος oldsee on 1 John 2:7, and compare “he was a murderer ἀπ ' ἀρχῆς fromthe beginning,” John 8:44; ἀρχή beginningbeing etymologically akin to ἀρχαῖος old The DevilSee on Matthew 4:1. [source]
Revelation 1:5 The faithful witness [ὁ μάρτυς ὁ πιστὸς]
For the phraseology see on 1 John 4:9. For witness, see on John 1:7; see on 1 Peter 5:1. As applied to the Messiah, see Psalm 89:37; Isaiah 55:4. The construction again departs from the grammatical rule. The words witness, first-born, ruler, are in the nominative case, instead of being in the genitive, in apposition with Jesus Christ. This construction, though irregular, nevertheless gives dignity and emphasis to these titles of the Lord. See on Revelation 1:4. The word πιστὸς , faithful is used (1), of one who shows Himself faithful in the discharge of a duty or the administration of a trust (Matthew 24:45; Luke 12:42). Hence, trustworthy (1 Corinthians 7:25; 2 Timothy 2:2). Of things that can be relied upon (1 Timothy 3:1; 2 Timothy 2:11). (2), Confiding; trusting; a believer (Galatians 3:9; Acts 16:1; 2 Corinthians 6:15; 1 Timothy 5:16). See on 1 John 1:9. The word is combined with ἀληθινός , true, genuine in Revelation 3:14; Revelation 19:11; Revelation 21:5; Revelation 22:6. Richard of St. Victor (cited by Trench) says: “A faithful witness, because He gave faithful testimony concerning all things which were to be testified to by Him in the world. A faithful witness, because whatever He heard from the Father, He faithfully made known to His disciples. A faithful witness, because He taught the way of God in truth, neither did He care for any one nor regard the person of men. A faithful witness, because He announced condemnation to the reprobate and salvation to the elect. A faithful witness, because He confirmed by miracles the truth which He taught in words. A faithful witness, because He denied not, even in death, the Father's testimony to Himself. A faithful witness, because He will give testimony in the day of judgment concerning the works of the good and of the evil.” [source]
