Sufficiency of Scripture

As a result of this many of His disciples withdrew and were not walking with Him anymore. 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.
