I read a true story about a young man who was called into the Civil war between the States. He made it back from the war without even a scratch. But when he got home, he learned that his father had died. He went out to the barn where his father used to milk the cows and saw a strange thing. He saw grooves in the board by the window. He asked his mother, what caused them. She said, son, every day, three time a day, you father went out there and prayed for your protection, and prayed that you would be saved. After hearing this, the boy fell on the boards and wept his way to God. Why? His father had prayed for him.
