John 6:28

24 So when the crowd saw that neither Jesus nor His disciples were there, they got into the boats and went to Capernaum to look for Him.

25 When they found Him on the other side of the sea, they asked Him, “Rabbi, when did You get here?”

26 Jesus replied, “Truly, truly, I tell you, it is not because you saw these signs that you are looking for Me, but because you ate the loaves and had your fill.

27 Do not work for food that perishes, 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.”

28 Then they inquired, “What must we do to perform the works of God?”

29 Jesus replied, “The work of God is this: to believe in the One He has sent.”

30 So they asked Him, “What sign then will You perform, so that we may see it and believe You? What will You do?

31 Our fathers ate the manna in the wilderness, as it is written: ‘He gave them bread from heaven to eat.’”

32 Jesus said to them, “Truly, truly, I tell you, it was not Moses who gave you the bread from heaven, but it is My Father who gives you the true bread from heaven.
