“Jesus answered them and said, ‘Most assuredly, I say to you, you seek Me, not because you saw the signs, but because you ate of the loaves and were filled. Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him.’” John 6:26-27.
“Then they said to Him, ‘What shall we do, that we may work the works of God?’ Jesus answered and said to them, ‘This is the work of God, that you believe in Him whom He sent.’” John 6:28-29.
“After this there was a feast of the Jews, and Jesus went up to Jerusalem. Now there is in Jerusalem by the Sheep Gate a pool, which is called in Hebrew, Bethesda, having five porches. In these lay a great multitude of sick people, blind, lame, paralyzed, waiting for the moving of the water. For an angel went down at a certain time into the pool and stirred up the water; then whoever stepped in first, after the stirring of the water, was made well of whatever disease he had.” John 5:1-4.
