The above verse states one can only come to salvation if The Father draws them. How would an unbeliever persuade God to draw them unto Himself so they can be saved? Is it a simple matter of asking Him, or would that contradict the "radical depravity" of man since no one seeks God?
John 6:44, as well as, verses 37, 39, 65 & 70 all seem to clearly state that God sovereignly chooses who will come to Jesus and that He will not lose any of them.
John 6:44 is especially strong, in that, Jesus says that no one comes to Him unless it has been granted to him by the Father. But, is this election to eternal life? Or to something else altogether?
In
John 6:66, some of those who were following Jesus did in fact turn away and stop following. If Jesus loses none of those who come to Him, how is it that some of those who came to Him stopped following Him? And in
John 6:70, Jesus says that He chose all twelve of His disciples and that one of them is a devil. If election, spoken of here, is to eternal life, then
John 6:70 contains the strange teaching that Jesus elected Judas to eternal life, knowing that Judas was/would be controlled by the devil. Jesus states that He chose all twelve, including Judas. It makes much more sense to realize that election, here, is not to eternal life, but to purpose and service. Only in this way can we allow for Judas to be chosen/elected by Jesus, as Judas did serve a very special role and purpose within the ministry and mission of Jesus.
