John 6:25-29

And when they found Him on the other side of the sea, they asked Him, “Rabbi, when did You get here?” Jesus answered, “I assure you and most solemnly say to you, you have been searching for Me, not because you saw the signs (attesting miracles), but because you ate the loaves and were filled. Do not work for food that perishes, but for food that endures [and leads] to eternal life, which the Son of Man will give you; for God the Father has authorized Him and put His seal on Him.” Then they asked Him, “What are we to do, so that we may habitually be doing the works of God?” Jesus answered, “This is the work of God: that you believe [adhere to, trust in, rely on, and have faith] in the One whom He has sent.”
