The point of these two illustrations was that God is aware of more insignificant things than the disciples, yet He has concern for these things. It is an argument from the lesser to the greater (cf. Luke 11:13). Since God knows about and has concern for these less important things, He will surely care for the disciples. The cent (Gr. assarion) was a Roman coin worth about one sixteenth of a denarius, a day"s wage (cf. Matthew 10:29). These illustrations balance Jesus" singular warning to fear God ( Luke 12:5) with a double assurance of His fatherly concern for disciples. However the Father"s intimate acquaintance with their lives also constitutes a warning against hypocrisy. [source][source][source]
