Blind people are sensitive to voice. They have listening skills, and they can be guided by words. When visibility is not clear, ears become hyper-sensitive and help a person including the blind to navigate through the situation. Peter was not able to recognize the Lord, for the disciples perceived Him as a ghost walking on water. (Matthew 14:22-233)
Promises:
First, the Lord had asked them to go ahead and cross the Sea of Galilee. He promised them to join later. Second, the Lord had promised to join them. He did not tell them when he would join in the midway or after they crossed and reached their destination.
Perception:
During the night (between 3 and 6 AM), as they rowed the boat, they could recognize someone coming towards them. The expert disciples immediately perceived that the person must be a ghost. As in many cultures, it is assumed that people who die unnatural deaths like drowning may roam the spirit realm as ghosts for a certain time. Perhaps, some fishermen knew someone who had drowned recently.
Presumption and faith:
To assure the distraught disciples, the Lord said: “It is I, do not be afraid.” Hearing the Words of the Lord, assured them, with some doubt lingering in their minds. Peter wanted to test and asked if it was the Master, let him command him to walk on the water towards Him. The Lord commanded Peter to come. He walked a few steps, he could not trust, as he shifted focus from the Lord to the tumultuous water and started sinking.
Power of restoration:
In despair, he shouted unto the Lord. He extended His hand and lifted Peter and rebuked him for his lack of faith. Now, where did Peter stand? On the same water, he was sinking a few minutes ago. Holding the Lord, Peter’s faith was restored, he could stand. Both could walk back to the boat. The disciples moved from fear to worship.
Purpose of God:
The Lord used this event to teach Peter and other disciples to walk in faith.
Do I walk in faith in risky, dangerous, and drowning situations?
