Matthew 9:6 But that you may know that the Son of Man has authority on earth to forgive sins? then He said to the paralytic, Rise, take up your bed and go to your house. (7) And he rose and went away to his house.
The Lord's salvation not only forgives our sins, but also causes us to rise and walk. It is not to rise and walk first and then be forgiven of our sins; that would be by works. Rather, it is to be forgiven of our sins first and then to rise and walk; this is by grace.
To forgive sins is a matter of authority on earth. Only this kingly Savior, who had been authorized by God and who would die to redeem sinners, had such authority. This authority was for the establishment of the kingdom of the heavens.
The Lord enabled the paralytic not only to walk, but also to pick up his bed and walk. Formerly the bed bore him; now he bears it. This is the power of the Lord's salvation.
This paralytic was brought to the Lord by others, but he went home by himself. This indicates that it is not that the sinner can go to the Lord, but that the sinner can go from the Lord by the Lord's salvation. The paralytic's rising and going proved that he was healed, and his being healed proved that his sins were forgiven.
This was a strong proof that the Lord Jesus had the authority to forgive people's sins.
