John 6:66.
John 6:65 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.”66 As a result of this many of His disciples withdrew and were not walking with Him anymore67. So Jesus said to the twelve, “You do not want to go away also, do you?”
68Simon Peter answered Him, “Lord, to whom shall we go? You have words of eternal life. 69We have believed and have come to know that You are the Holy One of God.
Peter GOT it... jesus had THE WORDS of eternal life.. He did not ask for this bread..He knew that life was in the word of God
