Painfully aware of their sin and confronted by the Bible’s warnings about falling away, people can sometimes be tempted to think that they are no longer Christians. In this booklet, Dr. R.C. Sproul looks at the Scriptures to see if a true Christian can ever fall away from the faith. He addresses topics such as the unforgivable sin, false converts, and the presence of sin in the lives of believers in this world. When Christians rely on God’s promise to preserve them to the end, they gain assurance of their salvation. The Crucial Questions booklet series by Dr. R.C. Sproul offers succinct answers to important questions often asked by Christians and thoughtful inquirers.
