Why do some people miraculously find Jesus, share their testimonies fervently, and then fall away? How have others professed Christ since childhood, preached sermons, and never found salvation, peace of mind, or joy?
Some sacrifice everything and keep believing, or suffer unspeakable never-ending pain and still praise the Lord? Despite their circumstances, like Job, they say, “though He slay me, yet will I trust Him.”
Billy Graham and Charles Templeton went to school together and stood before thousands spreading the good news of salvation. They were best friends. Charles went on to refute God and never returned. Billy Graham became an instrument of power in the hands of God.

Tell me, what makes the difference?
