From Mormonism to Christ's grace

Above is the story of a young Mormon missionary who read the Bible in a childlike way and became born again, resulting in a sharp split with the Mormon church. This fellow convinced his good friend, his Mormon girlfriend, his parents -- his dad a Mormon priest and his mom a Brigham Young University professor -- and his brother to become born again by accepting Jesus' pardon and direct love, which is at variance with the Mormon doctrine of salvation by works.
The trouble with salvation by works is that it's like trying to pay off your loan shark. The harder you try, the deeper in debt you get, until at last you're either enslaved or dead.
