“All that the Father gives Me will come to Me, and the one who comes to Me I will certainly not cast out. “For I have come down from heaven, not to do My own will, but the will of Him who sent Me. “This is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day. “For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day.”
(John 6:37-40 NASB)
“No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day. “It is written in the prophets, ‘AND THEY SHALL ALL BE TAUGHT OF GOD.’ Everyone who has heard and learned from the Father, comes to Me.
(John 6:44-45 NASB)
“But there are some of you who do not believe.” For Jesus knew from the beginning who they were who did not believe, and who it was that would betray Him. And He was saying, “For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father.”
(John 6:64-65 NASB)
So Jesus said to the twelve, “You do not want to go away also, do you?” Simon Peter answered Him, “Lord, to whom shall we go? You have words of eternal life. “We have believed and have come to know that You are the Holy One of God.” Jesus answered them, “Did I Myself not choose you, the twelve, and yet one of you is a devil?” Now He meant Judas the son of Simon Iscariot, for he, one of the twelve, was going to betray Him.
(John 6:67-71 NASB)
