5 And when Jesus saw their faith [their confidence in God through Him], He said to the paralyzed man, Son, your sins are forgiven [you] and put away [that is, the penalty is remitted, the sense of guilt removed, and you are made upright and in right standing with God].
[Upon His arrival] they brought to Him a man afflicted with a paralytic disease, [being carried on his cot. See Mark 2:3]. When Jesus saw [the evidence of] their faith [i.e., the man’s four friends breaking open the roof and lowering him through it. See Mark 2:4-5], He said to the paralytic, “Son, cheer up, your sins are forgiven.”
And if their prayer is [offered] by faith, [God] will heal the one who is sick, and the Lord will raise him up [from his sickbed]. And if he had sinned, he will be forgiven for them [Note: This may imply that the man’s sickness was the result of some sin. In any event, his forgiveness would follow his repentance].
For you have been saved by God’s unearned favor, through [your] faith, and that [salvation] was not the result of your own doing; it was the gift from God.
But God exalted Him at His right side to be a Prince and Savior and to give the people of Israel [an opportunity] to repent [i.e., change their hearts and lives] and [receive] forgiveness of [their] sins [through Him].
Later on Jesus found the man in the Temple, and said to him, “Look, you have been made well; stop sinning or else something worse [i.e., than the handicap you had] will happen to you.”
Tolerate one another’s [weaknesses] and forgive each other if anyone [of you] has a complaint against someone else. You should forgive people just as the Lord forgave you.
Now whomever you forgive [for doing] anything [wrong], I will forgive also. For indeed, whatever I have forgiven, if I have [actually] forgiven anything, has been for your sakes in the sight of Christ. [Note: Paul seems to be saying “Since my forgiveness depends on your forgiveness of the man, I am not sure of my forgiveness because I am not sure of yours”].
Because of this [i.e., their improper partaking of the Supper], many people among you are weak and ill, and a number have fallen asleep [i.e., died]. [Note: While most commentators view this judgment as physical, there is a distinct possibility that it refers to spiritual sickness and death].
When he got there and saw how God was favoring the people [with salvation] he was very happy and [stayed on and] encouraged everyone to remain close to the Lord with a heartfelt purpose.
