The Freedom of the Christian was Martin Luther's first public defense of the doctrine of justification by grace through faith on account of Christ alone. Luther's explosive rediscovery of the Gospel of Jesus Christ shattered the Church of Rome's foundation of works, which considered good works a part of salvation instead of a result of it. Here, Luther constructed a rich theology that relies on the full power of the Gospel, which not only grants saving faith but also nurtures that faith through good works done in the freest service.

While many of us struggle to understand it, the Trinity is one of the most important teachings of the Christian faith. It defines God's very essence and describes how he relates to us. And while it can be a difficult concept to get our heads around, it is crucial for believers to understand how God explains his triune nature in his word. In this book, James R. White offers a concise, understandable explanation of what the Trinity is and why it matters. 

What Is Reformed Theology? is an accessible introduction to beliefs that have been immensely influential in the evangelical church. In this insightful book, R. C. Sproul walks listeners through the foundations of the Reformed doctrine and explains how the Reformed belief is centered on God, based on God's word, and committed to faith in Jesus Christ. Sproul explains the five points of Reformed theology and makes plain the reality of God's amazing grace. 

In this famous treatise, St. Augustine (AD 354 - 430) covers the question of the role of free will in our lives and how it contrasts with the role of God's grace. He gives scriptural arguments to show that we cannot earn the grace of God, yet this does not deny the role that free will plays in our own salvation.

Sinners in the Hands of an Angry God is a classic sermon by Jonathan Edwards, first delivered in Massachusetts in 1741. This rendition is beautifully narrated by John Potter.

After his wife and children refuse to join him, he sets forth alone into the unknown.

But as he reaches Mount Zion, his family chooses to follow the same treacherous path, hoping to join Christian in the shining light.

Institutes of the Christian Religion is John Calvin's seminal work on Protestant systematic theology. Highly influential in the Western world and still widely read by theological students today, it was published in Latin in 1536 and in his native French in 1541. The book serves as an introductory textbook on the Protestant faith for those with some previous knowledge of theology and covers a broad range of theological topics from the doctrines of church and sacraments to justification by faith alone and Christian liberty.

By any standard, this is a classic of Christian theology. Composed by St. Athanasius in the fourth century, it expounds with simplicity the theological vision defended at the councils of Nicaea and Constantinople: that the Son of God himself became "fully human, so that we might become god."

A Praying Life is an honest look at the difficulties of prayer, unanswered prayers, and successes in prayer. Readers will appreciate Paul Miller's down-to-earth approach and practical nature. Parents will find his family-life experiences especially helpful.

Two years before he died, St. Thomas Aquinas, probably the greatest teacher the Church has ever known, was asked by his assistant Brother Reginald to write a simple summary of the faith of the Catholic Church for those who lacked the time or the stamina to tackle his massive Summa Theologica. In response, the great saint quickly set down in language that non-scholars can understand his peerless insights into the major topics of theology: the Trinity, Divine Providence, the Incarnation of Christ, the Last Judgment, and much more.
