It all began when Andrew was born again at just eight years old. Although he avoided the rebellious phase often associated with adolescence, he believed that through his own righteousness, he could develop a relationship with the Lord. Then, on a Saturday night in 1968, everything changed. Andrew realized he had fallen into the bondage of legalism and began confessing his self-righteousness, expecting the wrath of God to fall. But instead of wrath, God’s presence flooded him with love. "God's love consumed me," he says. "When I was at my worst, God's love was the strongest." This encounter changed his life forever and motivated him to follow God's leading in his life. He decided to leave college, even though that meant losing his student deferment. Drafted into the Army and shipped to Vietnam, he served as a chaplain's assistant. Despite how difficult and dangerous things were on the front lines, God used that time to ground Andrew in His Word and begin establishing the course of his life.
Upon his return, Andrew submitted to the call of God to be a teacher of His Word. He and Jamie were married in 1972, and together they began teaching Bible studies. Over the next six years, they would pastor three small churches and complete their family with two sons, Joshua and Jonathan Peter.
In 1976, Andrew broadcast his first Gospel Truth radio program on a little country-and-western station in Childress, Texas. By 1980, Andrew and Jamie had moved their ministry to Colorado Springs. Their vision was becoming quite clear: to teach the truth of the Gospel to the body of Christ throughout the United States and the world with special emphasis on God's unconditional love and the balance between grace and faith. They were fulfilling that vision by traveling to speaking engagements, producing radio broadcasts, and distributing audio cassette tapes, which were provided at no cost to those who could not afford them.
