Happy is our sacrament of water, in that, by washing away the sins of our early blindness, we are set free and admitted into eternal life! A treatise on this matter will not be superfluous; instructing not only such as are just becoming formed (in the faith), but them who, content with having simply believed, without full examination of the grounds of the traditions, carry (in mind), through ignorance, an untried though probable faith.

And so he gathered together a people for himself, and fostered them with many liberal distributions of his bounty, and, after so often finding them most ungrateful, ever exhorted them to repentance and sent out the voices of the universal company of the prophets to prophesy. By and by, promising freely the grace which in the last times he was intending to pour as a flood of light on the universal world through his Spirit, he bade the baptism of repentance lead the way.

This classic by St. Basil the Great (329-379) gives eloquent exposition of the doctrine of the Trinity, showing how there is distinction and yet communion among the divine Persons. Although not the Spirit "God", St. Basil demonstrates that he, like the Son, shares the same nature as the Father.

J. Gresham Machen once said, "False ideas are the greatest obstacles to the reception of the Gospel" - which makes apologetics that much more important. Wanting to engage not just academics and pastors but Christian laypeople and seekers, William Lane Craig has revised and updated key sections in this third edition of his classic text to reflect the latest work in astrophysics, philosophy, probability calculus, arguments for the existence of God, and Reformed epistemology.

Few subjects are as compelling-or as endlessly variable-as love and marriage. The Bible is filled with references to husbands and wives, from the story of Adam and Eve to advice in the New Testament, each open to interpretation. In The Meaning of Marriage, Timothy Keller, pastor of New York's Redeemer Presbyterian Church and bestselling author of The Reason for God, uses the scriptures as his guide to show readers what God's call to marriage is, and why this is such a powerful call.

In Seeking Allah, Finding Jesus, now expanded with new bonus content, Nabeel Qureshi describes his dramatic journey from Islam to Christianity, complete with friendships, investigations, and supernatural dreams along the way. Providing an intimate window into a loving Muslim home, Qureshi shares how he developed a passion for Islam before discovering, almost against his will, evidence that Jesus rose from the dead and claimed to be God.

A Body of Divinity, considered a classic among 17th-century Puritan works, contains a series of sermons on the Westminster Catechism, a central catechism in English-speaking Calvinist churches. Watson details several of the questions and answers from the Catechism.

A lifelong pursuit of knowing God should embody the Christian's existence. According to eminent theologian J.I. Packer, however, Christians have become enchanted by modern skepticism and have joined the "gigantic conspiracy of misdirection" by failing to put first things first. Knowing God aims to redirect our attention to the simple, deep truth that to know God is to love His Word.

Written after the capture of Rome in 410 by Alaric, King of the Visigoths, St Augustine's City of God was intended as a response to pagan critics who blamed Christianity for this brutal defeat. Augustine attacks ancient pagan beliefs and relates the corruption and immorality that led to Rome's downfall, which began before Christ, before reaching his main argument: that the City of Man is perishing and only the Heavenly City of God will endure.

The book of Revelation was written to do just that: reveal. In this commentary, Douglas Wilson provides a passage-by-passage walkthrough of the entire book, showing how John’s most notorious prophecies concern the Fall of Jerusalem in AD 70. Explaining symbols and characters as he goes, Wilson shows from the text that not only is this book not an elaborate code, but that Revelation is not even ultimately concerned with the end of the world as we know it. Revelation is about the triumph of the Church, which always happens when the Man comes around.

In his latest book, Angels, Dr. Heiser reveals what the Bible really says about God's supernatural servants. Heiser focuses on loyal, holy heavenly beings because the Bible has a lot more to say about them than most people suspect. Most people presume all there is to know about angels is what has been passed on in Christian tradition, but in reality, that tradition is quite incomplete and often inaccurate. Angels is not guided by traditions, stories, speculations, or myths about angels.

The Book of the Pastoral Rule (Liber Regulae Pastoralis) is a treatise on the duties of the clergy written by Pope Gregory I (540 - 604 A.D.) about AD 590, shortly after he was ordained as pope. This book would go on to become one of the most influential works ever composed on the subject. The book itself is addressed to John, the bishop of Ravenna, and is divided into four parts.

The Apostolic Fathers are the Christian writers from the first and second centuries who are thought to have been disciples of the Apostles or to have been so directly influenced by the Apostles that their writings are considered echoes of genuine Apostolic teaching. Their writings form a link of tradition that binds these writings to those of the New Testament. Chief among the apostolic fathers are the three first-century Bishops: St. Clement of Rome, St. Ignatius of Antioch, and St. Polycarp of Smyrna, who were disciples of St. Peter and St. John.

A Heavenly Conference is Richard Sibbes' exposition of the memorable meeting that took place on the first Easter Sunday when the risen Christ met Mary Magdalene at the empty tomb. Though only a few words were exchanged between the Lord and Mary, Sibbes saw in them the gospel in a nutshell. A Heavenly Conference is a wonderfully original treatment of the doctrine of the believer's union with Christ. It is written by a loving and tender-hearted pastor whose main aim is to help believers enjoy the comfort that comes from knowing that Jesus' God and Father is our God and Father too.

One of the great early Christian writings of the second century, The Demonstration of the Apostolic Preaching is a book all true believers can learn from. In writing to his friend, Irenaeus unfolds the Christian faith by quoting extensively from the Old Testament.
