G. Campbell Morgan was once approached by a soldier who said he would give anything to believe that God would forgive sins, "but I cannot believe He will forgive me if I just turn to Him. It is too cheap."
Dr. Morgan said to him: "You were working in the mine today. How did you get out of the pit?"
He answered, "The way I usually do; I got into the cage and was pulled to the top."
"How much did you pay to come out of the pit?"
"I didn't pay anything."
"Weren't you afraid to trust yourself to that cage? Was it not too cheap?"
The man replied, "Oh, no! It was cheap for me, but it cost the company a lot of money to sink that shaft."
The man saw the light, that it was the infinite price paid by the Son of God for our salvation, which comes to us by faith and not by anything that we can do.
