Commentary on Matthew 19:26

• John Calvin (Reformed), Calvin's Commentaries on Matthew 19:26: 26. With men this is impossible. Christ does not entirely free the minds of his disciples from all anxiety; for it is proper that they should perceive how difficult it is to ascend to heaven; first, that they may direct all their efforts to this object; and next, that, distrusting themselves, they may implore strength from heaven.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Matthew 19:26: But Jesus beheld them,.... Looking wishfully and earnestly at them; signifying thereby, that he knew their reasonings among themselves, though they did not speak out so as to be heard by him; and that there was no reason why they should be in so much concern, as their countenances showed, or possess themselves with such fears: and said unto them, with men this is impossible.
• William Burkitt (Anglican), Expository Notes on the New Testament on Matthew 19:26: As if Christ had said, "Were all men left to themselves, no man, either rich or poor would be saved; but God can bring men to heaven by the mighty power of his grace: he can make the rich in estate, poor in spirit; and them that are poor in this world, rich in grace."
