In 2 Kings 5:7, when Naaman came to the king of Israel to be healed of his leprosy, the king responds by tearing his clothes and saying: "Am I God, to kill and to make alive, that this man sends a man to me to heal him of leprosy?" Leprosy was incurable, according to the known means of man. It was understood that only God could cure leprosy. In Matthew 8:3 that is exactly what our Lord Jesus did! For, our Lord Jesus is God! And we, leprous sinners, must have nobody less than Jesus to save us also from our sins!
