Build Your Faith on a Solid Foundation

There's an invitation at the heart of the Christian life: not just to believe--but to understand. And as faith begins to grow, questions often follow. Not because something is wrong--but because something is maturing.

Who is God, really How can I trust the Bible What does it mean to follow Jesus

What once felt simple begins to invite you deeper--into a faith that is stronger, clearer, and built to last.

Essential Theology answers the foundational question: "What do I need to believe in order to be a Christian" Designed to deepen your understanding of Christianity in a clear and accessible way, this resource helps you build a firm foundation--one that strengthens your faith in everyday life.

Developed from the highly effective CORE training classes at Passion City Church, this resource unpacks the core truths every Christian should know:

The trinity and the attributes of God
The reliability of Scripture
Humanity and sin
The person and work of Jesus
Salvation and sanctification
The purpose of the church
Our future hope

Essential Theology challenges readers to see themselves as theologians--people learning about God--who are able to apply core truths to their everyday walk with Christ. If you want to move from uncertainty to assurance in what you believe, strengthen your ability to articulate your faith, and build a faith that's active and resilient, this book is for you.

Many Christians today are hungry for depth but don't have the time or resources to pursue a seminary-level education. CORE training resources, developed and written by pastors and leaders at Passion City Church in Atlanta, Georgia provide biblical foundations for spiritual growth for people of all ages.
