Fire is the best way to purify gold. When all the impurities are gone, you have 24-karat gold — the most valuable grade! One day, Jesus spoke of the value God places on his children. He said, "Don't be afraid of those who want to kill your body; they cannot touch your soul. Fear only God, who can destroy both soul and body in hell.
