What does John 6:44 mean?
This statement is nearly identical to Jesus' earlier words (John 6:37). This repetition supports the idea that the conversation which began in the streets of Capernaum (John 6:25) has moved into the synagogue (John 6:59). Jesus might simply be restating this for emphasis. He may be rephrasing it as part of a back-and-forth debate.This is the third time 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; 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 ultimately decides which persons are saved and which are not. Here, the language seems specific: only those drawn by God can come to Christ. Earlier, 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.
