And immediately, when Jesus perceived in his Spirit,.... "His own Spirit", as the Vulgate Latin, Syriac, Arabic, and Ethiopic versions read; not his human soul, nor the holy Spirit of God, though both may be said to be his Spirit; but his divine nature, in and by which he knew all things, even the most sacred thoughts of men's hearts: and as soon as ever the above thoughts were conceived in the minds of the Scribes and Pharisees, they were perceived by him, and told to them,

that they so reasoned within themselves; he said unto them, why reason ye these things in your hearts? thereby reproving them, not for reasoning and concluding in their own minds, that none but God can forgive sins; but for imputing blasphemy to him, for pronouncing this man's sins pardoned; he being God, as well as man, of which his knowing the thoughts and reasonings of their minds might have been a convincing proof.

Perceived (ἐπιγνοὺς)

The preposition ἐπί gives the force of fully. He was not only immediately aware of their thought, but clearly and fully aware.

And immediately when Jesus perceived in his spirit that they so reasoned within themselves, he said unto them, Why reason ye these things in your hearts?

2:2-12 Many were gathered together. For notes on the healing of this paralytic see Mt 9:2-8. Compare Lu 5:17-26. As we learn from Luke, among those gathered were Pharisees and scribes from Judea, Jerusalem, and Galilee (Lu 5:17), evidently by a preconcerted arrangement. The whole incident illustrates: (1) The Divine power of Christ. He could assert that he forgave sins without blasphemy. (2) The difference between Christ and his apostles, none of whom claimed to forgive sins (see Ac 8:22-24). (3) It affords a test for all priests who claim to forgive sin. If they possessed power to forgive sins they would have power also to relieve the body of the physical consequences of sin.

8. Why reason ye these things in your hearts-or, as in Matthew, (Mt 9:4) "Wherefore think ye evil in your hearts?"

2:1-12 It was this man's misery that he needed to be so carried, and shows the suffering state of human life; it was kind of those who so carried him, and teaches the compassion that should be in men, toward their fellow-creatures in distress. True faith and strong faith may work in various ways; but it shall be accepted and approved by Jesus Christ. Sin is the cause of all our pains and sicknesses. The way to remove the effect, is to take away the cause. Pardon of sin strikes at the root of all diseases. Christ proved his power to forgive sin, by showing his power to cure the man sick of the palsy. And his curing diseases was a figure of his pardoning sin, for sin is the disease of the soul; when it is pardoned, it is healed. When we see what Christ does in healing souls, we must own that we never saw the like. Most men think themselves whole; they feel no need of a physician, therefore despise or neglect Christ and his gospel. But the convinced, humbled sinner, who despairs of all help, excepting from the Saviour, will show his faith by applying to him without delay.
