In the same story of the paralytic, Jesus actually forgave the man's sins first. Then, knowing what the scribes and Pharisees were thinking in their hearts, to show that he truly had the authority to forgive sins, he ordered the man to rise, pick up his stretcher, and go home as well. The crowd was astonished and struck with awe. Who wouldn't be? Our Lord is authoritative, knows everything and exactly what he's doing. He is absolutely unique among all the religious leaders in history. If he is not truly God, then he must be the biggest liar who has ever lived. Again, Jesus challenges us.
