Then said Jesus unto him,
Except you see signs and wonders, you will not believe.
All Commentaries on John 4:48 Go To John 4
John Chrysostom
AD 407
Yet the very coming and beseeching Him was a mark of faith. And besides, after this the Evangelist witnesses to him, declaring that when Jesus said, Go, your son lives, he believed His word, and went. What then is that which He says here? Either He uses the words as approving of the Samaritans because they believed without signs; or, to touch Capernaum which was thought to be His own city, and of which this person was. Moreover, another man in Luke, who says, Lord, I believe, said besides, help my unbelief. And so if this ruler also believed, yet he believed not entirely or soundly, as is clear from his enquiring at what hour the fever left him, since he desired to know whether it did so of its own accord, or at the bidding of Christ. When therefore he knew that it was yesterday at the seventh hour, then himself believed and his whole house.
Do you see that he believed when his servants, not when Christ spoke? Therefore He rebukes the state of mind with which he had come to Him, and spoken as he did, (thus too He the more drew him on to belief,) because that before the miracle he had not believed strongly. That he came and entreated was nothing wonderful, for parents in their great affection are also wont to resort not only to physicians in whom they have confidence, but also to talk with those in whom they have no confidence, desiring to omit nothing whatever. Indeed, that he came without any strong purpose appears from this, that when Christ had come into Galilee, then he saw Him, whereas if he had firmly believed in Him, he would not, when his child was on the point of death, have hesitated to go into Judæa. Or if he was afraid, this is not to be endured either.
Observe how the very words show the weakness of the man; when he ought, after Christ had rebuked his state of mind, to have imagined something great concerning Him, even if he did not so before, listen how he drags along the ground.
