What does the Bible say about the authority of Jesus to forgive sins?

In Mark 2:5, Jesus illustrates his divine authority by forgiving the sins of a paralyzed man, a claim that shocked the scribes present, who recognized that only God has the right to forgive sins. This incident emphasizes the unique identity of Jesus as the Son of Man, endowed with the power to forgive sins on earth. It also shows that Jesus' authority extends beyond physical healing to the spiritual realm, affirming his role as the mediator between God and humanity, which is foundational in Reformed theology.
