How did Jesus cure the blind man in Bethsaida?

Mark 8:23-26 And he took the blind man by the hand, and led him out of the town; and when he had spit on his eyes, and put his hands upon him, he asked him if he saw ought.
And he looked up, and said, I see men as trees, walking.
After that he put his hands again upon his eyes, and made him look up: and he was restored, and saw every man clearly.
And he sent him away to his house, saying, Neither go into the town, nor tell it to any in the town.

The very wisdom that you can learn from optalmologist is when there is an operation of the eye to correct the way a person can see things especially those that are really blind but have the capacity to see again after operation there will be a period of recovery after the recovery the optalmologist will take the bandaid off the eye for the person who is blind to open his eyes very slowly and the first sight won't be as clear but the optalmologist will say just let a little time and you will surely see.

The Lord Jesus Christ disnot at once let the eye see He's really asking b but on the second touch of His hand the person have really seen every man, the wisdom is that to protect the eye which He restored by allowing a slow entrance of Life.
