John 6:55-71

For My flesh is true [spiritual] food, and My blood is true [spiritual] drink. He who eats My flesh and drinks My blood [believes in Me, accepts Me as Savior] remains in Me, and I [in the same way remain] in him. Just as the living Father sent Me, and I live because of the Father, even so the one who feeds on Me [believes in Me, accepts Me as Savior] will also live because of Me. This is the Bread which came down out of heaven. It is not like [the manna that] our fathers ate and they [eventually] died; the one who eats this Bread [believes in Me, accepts Me as Savior] will live forever.” He said these things in a synagogue while He was teaching in Capernaum. When many of His disciples heard this, they said, “This is a difficult and harsh and offensive statement. Who can [be expected to] listen to it?” But Jesus, aware that His disciples were complaining about it, asked them, “Does this cause you to stumble and take offense? What then [will you think] if you see the Son of Man ascending to [the realm] where He was before? It is the Spirit who gives life; the flesh conveys no benefit [it is of no account]. The words I have spoken to you are spirit and life [providing eternal life]. But [still] there are some of you who do not believe and have faith.” For Jesus knew from the beginning who did not believe, and who would betray Him. And He was saying, “This is the reason why I have told you that no one can come to Me unless it has been granted him [that is, unless he is enabled to do so] by the Father.” As a result of this many of His disciples abandoned Him, and no longer walked with Him. So Jesus said to the twelve [disciples], “You do not want to leave too, do you?” Simon Peter answered, “Lord, to whom shall we go? You [alone] have the words of eternal life [you are our only hope]. We have believed and confidently trusted, and [even more] we have come to know [by personal observation and experience] that You are the Holy One of God [the Christ, the Son of the living God].” Jesus answered them, “Did I not choose you, the twelve [disciples]? And yet one of you is a devil (ally of Satan).” Now He was speaking of Judas, the son of Simon Iscariot; for he, one of the twelve [disciples], was about to betray Him.
