Charles Spurgeon Commentary Matthew 9:6

"But that ye may know that the Son of man hath authority on earth to forgive sins (then saith he to the sick of the palsy), Arise, and take up thy bed, and go up unto thy house." — Matthew 9:6 (ASV)

The second part of the miracle was for the silencing of those fault-finding scribes, That you may know. Did they ever come to this knowledge? The case was made clear for them, but they would not see it. Jesus, the Son of man, was still on earth, but in His lowly condition He had authority and power to forgive sins against God, for He was God. He would prove that He had power on earth by healing the paralytic.

By exerting what they thought the greater power, He would prove His possession of the less. He commanded the man, Arise, or get up. He further says, take up your bed, or roll up your mat and lift it to your shoulders, and then walk. Thus would the obedient patient, by the free use of his limbs, prove himself to be wholly recovered. This was a great word to speak, but he, who had already received pardon from our Lord’s lips, felt no difficulty in believing it, and he found his faith justified.

If sin is forgiven, nothing is impossible. Surely it follows that if Jesus had power on earth to forgive sins, He can abundantly pardon now that we see Him as the Son of God, enthroned in heaven.
