This is what the Lord Jesus Christ has done. He made sure that he touched the eyes of the man for the second time because he is trying to let the eyes adapt into the situation and that’s just thw wisdom right there.
Let us read the Bible from Mark 8:22-25 which says;
And he cometh to Bethsaida: and they bring a blind man unto him, and besought him to touch him.
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 aught.
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
There is a wisdom in this verse of the Bible which we all should learn and be familiar with. It is that the eye doctor, after a successful eye surgery will ask his patient to open the eye slowly and with time, the blurry vision which the person is seeing will become clearer. That’s just exactly what Jesus Christ did to the blind man in Bethseda.
He made sure that the blind man opened his eyes gradually and slowly till his sight becomes normal and clearer.
If anyone has an eye surgery and the person looks directly into the sun, it is very possible to damage the eye again. This is how much light affects our eyes.
Also, another thing to learn from this is that Jesus Christ was and still the master healer. His way of opening the blind man’s eye is a miracle but after that process, the person had to carefully open his eye.
That’s a healing process which has been used by Jesus and now used by doctors.
