I Wonder Why

This morning I continued to read Mark 8. In this passage, Jesus restores sight to a blind man.

22They came to Bethsaida, and some people brought a blind man and begged Jesus to touch him. 23He 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?"
24He looked up and said, "I see people; they look like trees walking around."

25Once more Jesus put his hands on the man's eyes. Then his eyes were opened, his sight was restored, and he saw everything clearly. 26Jesus sent him home, saying, "Don't go into the village.[a]"

Today, I will walk around wondering about the following:

1) Why did Jesus spit, yes spit (ew) in the man's eyes? He could have touched him like the people asked, but he decided to spit! Why?
2) Why did Jesus gradually heal this man instead of healing him all at once? Moreover, why did the blind man see people that looked like trees walking around? Is there something significant to that?
3) When the, now, partially blind man was touched a second time, why didn't Jesus spit on his eyes again? He just touched him-- no spitting required. Interesting-- why? Also, why does Jesus ask if the man can see? Doesn't he know the man can't see yet?
4) Why did Jesus not want the man to go to the village? Was it because all the villagers would see that the blind man was healed and then chase Jesus down to either 1) kill Jesus or 2) ask him perform more healings? Did he not want to be known yet? Maybe he didn't want to be bugged?

Speaking of being bugged, the other night Doug Coe said, if we are the light of the world, then all the bugs of the world will be attracted to us. Which gave me understanding as to why I always have interesting encounters with rather odd people. ahahaha! I thought it was the greatest analogy. And I hope we are all being bugged!
