Mark 8:22-26
22 They came to Bethsaida, and some people brought a blind man and begged Jesus to touch him.
23 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?"
24 He looked up and said, "I see people; they look like trees walking around."
25 Once more Jesus put his hands on the man's eyes. Then his eyes were opened, his sight was restored, and he saw everything clearly.
26 Jesus sent him home, saying, "Don't go into the village."

Yet another man being healed here, this time of blindness. This healing story is different from many of the others. First, Jesus led the man out of town before performing the miracle and second, he needed two attempts before he was successful. Is there something wrong with Bethsaida? Some say that the residents of Bethsaida didn't believe in Jesus. Both Matthew (11:21-22) and Luke (10:13-14) record that Jesus cursed Bethsaida for not accepting him. Lack of faith is a repulse for Jesus.

Then we have to wonder why Jesus had difficulty making this miracle work. In the past he could speak a single word and have the dead walk or the mute speak. A person could, without his knowledge, be cured of a long-standing illness by merely touching the edge of his garment. So what happened here?

Some say that such a gradual restoration of physical sight represents the idea that people only gradually acquire the spiritual "sight" to truly understand Jesus and Christianity. At first, he sees in a way that is similar to how the apostles and others saw Jesus: dimly and distorted, not comprehending his true nature. After more grace from God works on him, however, full sight is received - just as grace from God can bring about full spiritual "sight" if we allow it.
