Faith Alone

Faith Alone by R.C. Sproul is a clear, classic exposition of the Reformation doctrine of justification — the belief that people are declared right with God solely by faith in Christ, apart from any merit or works of their own. Sproul explains the biblical and historical roots of sola fide (faith alone), why it was central to the Protestant Reformation, and why understanding this teaching is essential for grasping the true gospel today. The book offers both theological depth and readable insight into how faith in Christ’s righteousness, not human effort, brings salvation.
