26 Jesus answered them, "Truly, truly, I say to you, you are seeking me, not because you saw signs, but because you ate your fill of the loaves. 27 Do not labor for the food that perishes, but for the food that endures to eternal life, which the Son of Man will give to you. For on him God the Father has set his seal."
Matthew Henry's Commentary on John 6:26-27
Commentary on John 6:22-27
(Read John 6:22-27)
Instead of answering the inquiry how he came there, Jesus blamed their asking. The utmost earnestness should be employed in seeking salvation, in the use of appointed means; yet it is to be sought only as the gift of the Son of man. Him the Father has sealed, proved to be God. He declared the Son of man to be the Son of God with power.
