John 6:27

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.

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.”

Do read the surrounding verses too, because the context often says more than a single verse.
