John 6:44

οὐδεὶς δύναται. It is a moral impossibility: comp. John 3:3; John 3:5; John 5:44; John 8:43; John 12:39; John 14:17; John 15:4-5. The οὐδείς corresponds to the πᾶν in John 6:37, as ἑλκύσῃ to δίδωσιν: all that are given shall reach Christ; none but those who are drawn are able to come to Him. The aor. ἐλθεῖν expresses the result, rather than the process, as in τὸν ἐρχόμενον (John 6:37), and ἔρχεται (John 6:45).

ἑλκύσῃ. Comp. John 12:32, πάντας ἑλκύσω πρὸς ἐμαυτόν. Unlike σύρειν, ‘to drag’ (Acts 8:3; Acts 14:19; Acts 17:6), ἑλκύειν does not necessarily imply force, but mere attraction of some kind, some inducement to come. Comp. Jeremiah 31:3, ‘with lovingkindness have I drawn thee’ (εἵλκυσά σε), and Virgil’s trahit sua quemque voluptas. Ἑλκίσῃ expresses the internal process, δίδωσιν (John 6:37) the result.

κἀγώ. The Father begins the work of salvation, the Son completes it. The Father draws and gives; the Son receives, preserves, and raises up to eternal life.
