Book excerpt: God is holy, and we are sinful. God cannot stand to look upon sin. But the gospel of Jesus Christ reveals how sinful people can be right with God. In this booklet, Dr. R.C. Sproul delves into Scripture and church history to explore the doctrine of justification by faith alone. In so doing, he explains that by faith alone in Christ alone, sinful men and women can be justified and stand forgiven before a holy God. The Crucial Questions booklet series by Dr. R.C. Sproul offers succinct answers to important questions often asked by Christians and thoughtful inquirers.
