What does John 6:44 mean?
This statement is nearly identical to Jesus' words in verse 37. This near-repetition supports the idea that the conversation begun in John 6:25 has moved from the streets of Capernaum into the synagogue. Jesus might simply be restating this for emphasis, or rephrasing it as part of a back-and-forth debate.This verse marks a third time where Jesus repeats the idea that those whom God sends to Him will, undoubtedly, see eternal life (John 6:37; 39-40). This strongly supports the doctrine of eternal security, meaning that those who are truly saved cannot ever lose their salvation, under any circumstances. Once a person has come to faith in Christ, Christ will raise that person up to eternal life.
Like verse 37, this text also touches on the question of predestination—the idea that God is the one who ultimately decides which persons are saved and which are not. Here, the language seems fairly specific: only those drawn by God can come to Christ. In verse 37, it was stated that those who were "given" to Christ by the father would be saved. Of course, in the wide debates over predestination, there are alternative theories of how, who, and when exactly God "draws" people.
