John 6: 26 Jesus replied to them, Truly, I tell all of you emphatically, you are looking for me, not because you saw signs, but because you ate the loaves and were completely satisfied. 27 Do not work for food that perishes but for food that lasts for eternal life, which the Son of Man will give you, because God the Father has set his seal on him.
28 Then they asked him, What must we do to perform Gods works?
29 Jesus answered them, This is Gods work: to believe in the one whom he has sent.
