26 Jesus, answering them, said, Truly I say to you, You come after me, not because you saw signs, but because you were given the bread and had enough. 27 Let your work not be for the food which comes to an end, but for the food which goes on for eternal life, which the Son of man will give to you, for on him has God the Father put his mark.
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.
