Every Christian is responsible for knowing God’s Word and sharing it with others. But in a world affected by sin, false teaching is everywhere. Many people obscure, distort, or challenge what God has revealed in Scripture—even some leaders in the church. To be better prepared as witnesses for Christ, we must identify falsehood and the devastating harm it brings. By surveying prominent theological errors, cults, and world religions, this book can equip you to defend your faith against the dangers of false teaching. It can also help you more effectively respond to your friends, family, and neighbors with the hope you have in Christ.
