What does the Bible say about Jesus forgiving sins?

In the Gospel of Luke 5:17-26, we see Jesus forgives the sins of a paralytic man, which raises questions among the onlookers who wonder how a mere man could forgive sins. Jesus responds to their thoughts by asserting His divine authority to forgive sins, essentially revealing that He is indeed God. This passage illustrates the core belief that only God has the power to forgive sins, emphasizing Jesus' divinity. The miraculous healing of the man serves as confirmation of His authority as the Son of God.
