Why did Jesus spit on a blind man’s eyes?

They came to Bethsaida, and some people brought a blind man and begged Jesus to touch him. He took the blind man by the hand and led him outside the village. When he had spit on the man’s eyes and put his hands on him, Jesus asked, “Do you see anything?” Mark 8:22-23

            Jesus can heal anyway he wants to heal.  If one person could spit on you, wouldn’t you want it to be the righteous spit of Jesus?  Jesus healed in many different ways, this just shows the diversity and ability of God to do whatever he wants to do.
