As before ( Matthew 5:23-26), two illustrations aid our understanding. The eye is the member of the body initially responsible for luring us into an immoral thought or deed (cf. Numbers 15:39; Proverbs 21:4; Ezekiel 6:9; Ezekiel 18:12; Ezekiel 20:8). The right eye is the best eye, the common metaphorical use of the "right" anything. A literal interpretation of this verse would have Jesus crippling every member of the human race. Should not one pluck out his left eye as well? Furthermore disposing of the eye would not remove the real cause of the offense, a lustful heart. Clearly this is a hyperbolic statement designed to make a point by overstatement. The early church father Origen took it literally and castrated himself. Jesus" point was that His disciples must deal radically with sin. We must avoid temptation at all costs. Clearly this is not a condition for salvation but for discipleship. [1][source]
The reference to cutting off the "right hand" ( Matthew 5:30) is also metaphorical, but how symbolic is it? Some take the "right hand" as a euphemism for the penis (cf. Isaiah 57:8). [2] This view has the context in its favor. Others take the right hand literally and view it as the instrument of stealing another man"s wife. "Hell" is Gehenna, the final place of punishment for all the wicked. [3] Its mention here does not imply that believers can go there. It represents the worst possible destiny. It, too, is hyperbole. The loss of any body part is preferable to the loss of the whole person is the point. [source][source][source]
"Imagination is a God-given gift; but if it is fed dirt by the eye, it will be dirty. All sin, not least sexual sin, begins with the imagination. Therefore what feeds the imagination is of maximum importance in the pursuit of kingdom righteousness (compare Philippians 4:8). Not everyone reacts the same way to all objects. But if ( Matthew 5:28-29) your eye is causing you to sin, gouge it out; or at very least, don"t look ...!" [4][source]
