John 6:26-29

26Jesus answered, “Very truly I tell you, you are looking for me, not because you saw the signs I performed but because you ate the loaves and had your fill.

27Do not work for food that spoils, but for food that endures to eternal life, which the Son of Man will give you. For on him God the Father has placed his seal of approval.”

28Then they asked him, “What must we do to do the works God requires?”

29Jesus answered, “The work of God is this: to believe in the one he has sent.”
