How do we know that Jesus can forgive our sins?

The question of how we know Jesus can forgive sins is rooted in His identity as the Son of God and the consequent authority He possesses. In Matthew 9, Jesus knew the thoughts of those around Him, which only God could do, thereby affirming His divine nature. Furthermore, His miraculous acts—like healing the paralytic—serve as signs pointing to His greater power to forgive sins. The forgiveness offered through Christ is not arbitrary; it is grounded in His righteous blood shed for humanity, making it possible for God to remain just while justifying the ungodly (Romans 3:26).
