John 6:27-29

²⁷ Do not work for the food that perishes, but for the food that endures for eternal life, which the Son of Man will give you. For it is on him that God the Father has set his seal.” ²⁸ Then they said to him, “What must we do to perform the works of God?” ²⁹ Jesus answered them, “This is the work of God, that you believe in him whom he has sent.”
