Foundations of Faith: Understanding the Essential Truths Every Christian Should Know

George Barna's American Worldview Inventory, published March 28, 2025, found that only 16 percent of self identified Christians in the United States affirm the historic doctrine of the Trinity, and just 29 percent of Americans overall believe in the presence and power of the Holy Spirit. Barna called this a discipleship gap, not merely a knowledge gap. That gap is exactly what this book was written to close.

Foundations of Faith is not a survey of religious opinions. It is a clear, Scripture grounded walk through the twelve essential truths every Christian should know: the authority of the Bible, the character of God, the Trinity, sin and the fall, the person and saving work of Christ, salvation by grace through faith, the Holy Spirit and new birth, prayer, the church, baptism and the Lord's Supper, spiritual warfare, and the hope of Christ's return. Each doctrine is unpacked in plain, accessible language, never complicated for the sake of sounding impressive, because truth rightly taught produces clarity, not confusion.

This is discipleship material pastors can hand directly to new believers, teach through in small groups, or use to anchor a new members class, and it is equally suited to the longtime Christian who has never actually examined what they claim to believe. A believer who understands grace stops exhausting themselves trying to earn God's approval. Someone who grasps the character of God can trust Him in seasons that make no sense. A Christian who understands spiritual warfare stops being surprised by opposition and starts standing against it firmly.

By the final page, you will not simply know more about God. You will know Him more, standing on a foundation strong enough to carry you through anything life brings. Start building today.
