The Glory of God, the Power of Christ
Jesus performs the cure that they may know that the Son of man has authority on earth to forgive sins. His words about forgiveness and healing go together. If he can do the one he can do the other. The Jews of the day thought that all sickness was due to sin (cf. John 9:2). ‘R. Alexandri said in the name of R. Ḥiyya b. Abba: A sick man does not recover from his sickness until all his sins are forgiven him’ (Nedarim 41a). Had they been consistent, accordingly they must have accepted the man’s forgiveness!
Spurgeon wrote:
I think I see him! He sets one foot down to God’s glory, he plants the other to the same note, he walks to God’s glory … he carries his bed to God’s glory, he moves his whole body to the glory of God, he speaks, he shouts, he sings, he leaps to the glory of God.
