From Trimmer's A Description of a Set of Prints Taken from the New Testament: "Jesus spake unto them, saying, It is I, be not afraid. And Peter answered and said Lord, if it be thou, bid me come to thee on the water: and he said, Come. And when Peter was come out of the ship, he (through the power of CHRIST) walked on the water likewise; but when he saw the wind boisterous, his faith or belief in CHRIST'S power, failed, he was afraid, and beginning to sink, he cried out, Lord, save me! And immediately JESUS stretched forth his hand and caught him, saying, O thou of little faith, wherefore didst thou doubt?"
