This caused the Pharisees and scribes to think that Jesus was blaspheming for only God can forgive sins. Jesus then tells the man who was paralyzed to pick up his stretcher and go home. This leads to the last line: "We have seen incredible things today."
Now a German Benedictine mystic has this to say about God's mercy: " God's mercy is kind. God gives divine, abundant grace to those who love Him....No one can stop God's mercy,..' I think we all experience this, especially when we receive the Sacrament of Reconciliation. It is a real encounter with Christ and leaves me feeling the peace of His Presence for several days.
