While Jesus was staying at a house in Capernaum, a group of men tried to bring a paralyzed man to Jesus so that Jesus would heal him. But, there was a large crowd inside and outside of the house, so the men had to find a creative way to get the paralyzed man to Jesus. The men succeeded and Jesus miraculously healed the man.
As explained in the Gospel of Luke:
When Jesus saw their faith, he said, "Friend, your sins are forgiven."
The Pharisees and the teachers of the law began thinking to themselves, "Who is this fellow who speaks blasphemy? Who can forgive sins but God alone?"
Jesus knew what they were thinking and asked, "Why are you thinking these things in your hearts? Which is easier: to say, 'Your sins are forgiven,' or to say, 'Get up and walk'? But I want you to know that the Son of Man has authority on earth to forgive sins." So he said to the paralyzed man, "I tell you, get up, take your mat and go home." Immediately he stood up in front of them, took what he had been lying on and went home praising God. Everyone was amazed and gave praise to God. They were filled with awe and said, "We have seen remarkable things today."
- Luke 5:18-26, NIV translation.
Jesus is God incarnate as a man. He is fully human and he is fully God.
