The Christian faith enables us to face life or meet death, not because we can see, but with the certainty that we are seen; not that we know all the answers, but that we are known. -Donner Atwood.
"And he (JESUS) said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus."
Peter had the faith to get out of the boat, but then started to fear and thus started to sink
"And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?"
God saw Peter the whole time. He sees us the "whole time" too. In fact he says "Come" to Him. He even reaches out to us and gives us a way, through Jesus. We just have to have faith to take that step, to get out of the boat, to JUMP.
