Basing this work on his own full-scale Systematic Theology, Berkhof summarizes the body of church doctrine, beginning with the doctrines of Scripture and God and proceeding through statements on anthropology, Christology, soteriology, and more.

In this quick and vibrant little book, Kelly Kapic presents the nature, method and manners of theological study for newcomers to the field. He emphasizes that theology is more than a school of thought about God, but an endeavor that affects who we are. "Theology is about life," writes Kapic. "It is not a conversation our souls can afford to avoid."
