Guidelines International Ministries is a small ministry with a big God. In 1963, a young minister and his wife drove up into the Rockies of Colorado for some mountain air and and some time to pray. “How,” they asked God, “can we reach people most effectively with the message of the Gospel?” Harold & Darlene Sala believed that the answer was clear: “Use radio. This will enable you to touch lives of people wherever they are around the world and where missionaries cannot go.”
