Mark 8:22-26 Jesus Heals the Blind Man: The meaning behind seeing trees

When Jesus and his disciples arrived at Bethsaida,
people brought to him a blind man and begged Jesus to touch him.
He took the blind man by the hand and led him outside the village.
Putting spittle on his eyes he laid his hands on the man and asked,
"Do you see anything?"
Looking up the man replied, "I see people looking like trees and walking."
Then he laid hands on the man's eyes a second time and he saw clearly;
his sight was restored and he could see everything distinctly.
Then he sent him home and said, "Do not even go into the village."

 In this passage, Jesus touches the blind man and gives him sight. At first the blind man does not see clearly but after Jesus laid his hands upon him a second time he is able to see. This story represents our own spiritual journeys. So often we are called by Christ and attempt to respond but when we first respond we do not fully understand our vocation. It is not until we are called multiple times do we respond. We, like the disciples in the Gospel of Mark, and like the blind man, only see clearly after we encounter Christ multiple times.
