This artwork flips the perspective of Peter walking on water. Here we see Peter taking a step of faith towards the Lord, from the Lord’s perspective. Imagine how happy Jesus was to see one of his beloved disciples actually show that much faith and come towards him atop water, step by step. What an amazing example of FAITH Peter set for the other Apostles in the boat, and Christianity as a whole.
The Bible - New Testament: Matthew 14:28-29
28 And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water. 29 And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus.
