John 6:26-27

26Jesus 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.

27Do 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.”
