Of the world's 1 billion Muslims, a great number of have never heard the truth of the Gospel. They have never heard of God's grace and the salvation found in Jesus Christ. As followers of Jesus, we are commanded to make disciples of all nations. In making disciples, we must take the Gospel to Muslims. Unfortunately, many Christians are afraid to approach Muslims. Some of this fear is based in the "unknown" - Christians are unaware of what Islam teaches, they don't know what questions Muslims may have, and they don't have a good starting point for sharing the Gospel. Truth to Tell is designed to help Christians overcome the fear of the unknown so that they can develop relationships with Muslims. Through a systematic approach, Truth to Tell addresses the topics of God, Man, Sin and Salvation in both Christianity and Islam. This allows Christians see common themes and contrasts in the beliefs of these two religions and provides the starting point for sharing the Gospel. It also helps Christians to anticipate questions that Muslims may have about Christianity.
