'Be of good courage, son'!
Jesus asked:' Which is easier to say to the paralytic, "Your sins are forgiven" or to say:" Get up an walk?" (Matthew 9,2).
Anybody may pretend to fogive sins - without being possible to tell whether the sins were forgiven or not. But who could say "get up", and give effect to his words, without a power from above? Jesus healed this paralytic by a word, and it was clear that He was the One who had also power on earth to forgive sins!
The unanswerable question was received with the silence of an invincible obstinacy. But turning once more to the paralytic, Jesus said to him, "Get up, take your mat and go home". At once power was restored to the palsied limbs, peace to the stricken soul. The man was healed.(Dean Farrar, The Life of Christ)
