After his resurrection, Jesus gave his disciples a mission: to go to all the nations and make disciples, baptizing and teaching them. That remains the continuing mission of the church today. In this book, R.C. Sproul explores the Great Commission by laying out the biblical basis for missions, defining the gospel and evangelism, and addressing the need to mobilize Christian believers for missions. He also touches on methods of evangelism, while pointing ultimately to the one who promised that he would build his church. This book is a challenge to the church and to individual Christians to obey Jesus’ command to go and make disciples.

Can I Lose My Salvation?

  • Author: R.C. Sproul

Whether you can lose your salvation is one of the most pressing issues Christians face. In an uncertain world, painfully aware of the continued reality of their sin, and confronted by the Bible’s warnings about falling away, Christians can be tempted to think that true believers can lose their salvation.

In this book R.C. Sproul looks at the teachings of Scripture on the doctrine of eternal security or the perseverance of the saints. In looking at passages on the unforgivable sin, believers who have departed, and the continuing presence of sin in the lives of Christians, Sproul ultimately points to the promises of God, who has vowed to preserve to the end those who are in Christ.

    See my review of the full set. All of the late Dr. Sproul's CQ primers are excellent introductions to theological topics. They are short and written primarily for laymen.
