Jesus makes a point of asserting His authority to forgive sins, connecting it to His obvious ability to heal.
Jesus takes of His authority and gives it to the 12 apostles, whom He sends out as sheep among wolves to heal, exorcise and resurrect the dead. He warns them to have no fear of man, but to speak the truth about Jesus, the Christ before men. This will bring a sword and a cross for the speaker, not peace. But there will also be rewards for His disciples.
