Before WWII, Warren lived in a dream world of art and music. But when he saw 185 shipmates get killed by a torpedo in the Pacific, his eyes were opened to the terrible forces of evil that are destroying the world. At age 29, he had a sweet wife who loved him, a new baby boy, and he became born again. Realizing Jesus is the only solution for this sin-sick world, he dreamed of doing big things for God—like preaching to multitudes á là Billy Graham. But the Lord had other plans for him.
Although he supported his family as an advertising artist and part-time musician, God began to use his witness in unique ways. Upon retiring, he began an open-air ministry called Operation Salt and Light. Now, some of his activities include ministry every Sunday morning to juveniles in a detention facility in Southern Maryland, leading small group studies in evangelism at church, and motivational talks to Christians.
