I have had questions about God and the Christian faith from the time of my conversion, and for years, I feared that such questions meant there was something wrong with my faith. Then I discovered God’s invitation in Isaiah 1: “Come now, let us reason together, says the LORD” (v. 18). “Reason together” in the Hebrew means “argue it out.” I found Thomas, whose honest questions about the resurrection were welcomed and answered by his risen Lord (John 20:24–29).Most of all, I was encouraged by Jesus’ own example when he cried from the cross, “My God, my God, why have you forsaken me?” (Matthew 27:46). If our sinless Savior could ask questions of his Father, surely we can.This small booklet is the second in a series on tough faith questions. In this volume we ask these ten questions: Why do we believe that the Bible is actually the Word of God?What are angels? Will I become one?Is there really a creature named Satan?Are there really demons?Are we living in the "end times"? How do we know?What are your spiritual gifts? Are they the same as talents?How can I share my faith with others? Why should I?Can I really overcome temptation and sin?If God knows everything, why should I pray?Why does God want to be worshipped? How can I worship him best?Biblical scholar William Barclay noted, “If a man fights his way through his doubts to the conviction that Jesus Christ is Lord, he has attained to a certainty that the man who unthinkingly accepts things can never reach.”May this booklet help you find such certainty that you are empowered to share your faith with a doubting world, to the glory of God.
