"I CAN SEE YOU."
During the bombing of London during WW2, the Nazis would nightly bomb buildings and homes of civilians.
A father, holding his small son by the hand ran from a building that had been struck by a bomb. In the front yard was a shell hole. Seeking shelter as quickly as possible, the father jumped into this deep dark hole and held up his arms for his son to follow.
It was dark in the hole and the boy couldn't see his dad. Terrified, yet hearing his father's voice telling him to jump, the boy replied, "I can't see you!"
The father, looking up against the sky tinted red by the burning buildings, called to the silhouette of his son and said, "But I can see you. Jump!"
The boy jumped because he knew his dad and he had faith in him.
