Jesus performs the visible miracle as evidence of His invisible authority. The physical healing is a 'sign' pointing to a greater spiritual reality: He has power to forgive sin itself.
Memory phrase: The Son of Man forgives sins
Talk about it: Jesus healed the man to prove He could forgive sins. Which healing do you think was greater?
Prayer: Jesus, Son of Man, You have all power on earth and in heaven. I trust You with my whole life.
