When they had rowed about three or four miles, they saw Jesus walking on the sea and drawing near to the boat. They were frightened, but he said to them, "It is I; do not be afraid."

John 6:19-20

"For I have learnt for a fact that nothing so effectively obtains, retains and regains grace, as that we should always be found not high-minded before God, but filled with holy fear."

– St. Bernard
