Contend: Defending the Faith in a Fallen World

contend working final front big

Jesus said, “I am the way, and the truth, and the life. No one comes to the Father except through me” (John 14:6). With the entire Christian faith standing or falling on the validity of such an utterly exclusive and uncompromising claim, doctrine that truly aligns with Jesus will cause division. When we represent our faith honestly, it is simply inevitable: at times we will be at odds with others—friends, relatives, perhaps even other Christians. Yet we are called to contend, in obedience to and for the sake of the most divisive person in history. And the challenge is to do it in the way Jude describes: as an act of mercy toward those who doubt and those who have been deceived, regardless of whether they claim faith in Christ.

Contend, by one of evangelicalism’s most promising young writers and thinkers, is exactly the kind of book the church needs in our moment. We are tempted today on every side to be meek as a mouse. Christianity is many things, but it is not—it cannot be—anodyne. Armstrong’s gospel-saturated writing, coupled with deeply instructive practical examples, will equip the church to be as bold as a lion, and to roar as Luther, Calvin, Spurgeon and Machen before us.”

Owen Strachan, Assistant Professor of Christian Theology and Church History, Boyce College; coauthor, Essential Edwards Collection

“At a time of great theological confusion and emotional calls to content-less “unity,” a time of politically-correct “can’t-we-all-get-alongism,” here is a balanced and passionate appeal especially to young believers from a young author, Aaron Armstrong, to take seriously their commitment to Jesus in all areas of life, both individually and in community, contending for the Faith, using both their minds and their hearts in defense of the Truth, in the manner laid out by the apostle Jude. May this call be heard far and wide.”

Contend is a fine combination of concise biblical exposition, down-to-earth examples, contemporary illustrations, and challenging practical application. I’ve already made a list of people I want to give this to…as well as another list of areas to work on in my own life and ministry. It’s not only an ideal book for discipling a new believer, but also for shaking the more mature out of dangerous complacency and passivity.”

David P. Murray, Professor of Old Testament and Practical Theology, Puritan Reformed Theological Seminary

“Some church leaders like myself get a queasy stomach when faced with theological conflicts. Others relish the fights and want to convene a church council over the number of Adam’s hairs. Aaron presents a third way between avoidance and division: the biblical model of earnest, charitable contending for the faith. This is a book the Church desperately needs, for it matters not merely that we contend, but also how we contend and that we contend for the right cause: namely the name of Christ. Contend not only calls us to defend orthodoxy, but gives us a biblical blueprint for doing it. I wholeheartedly recommend this book to pastors, seminarians, bloggers, and teachers.”

Daniel Darling, Senior Pastor, Gages Lake Bible Church; Author, Real: Owning Your Christian Faith

“The very idea of contending is contentious. But the costs of not contending for the faith are high, and we’d better learn when and how to defend what matters most. With clarity and insight, Aaron Armstrong helps us understand why it’s hard to take a stand, what’s worth fighting for, and how to do it. I’m grateful for this biblical and helpful book.”

Darryl Dash, Pastor, Liberty Grace Church, Toronto ON; blogger,

“While some think that defending the faith is the task of scholarship and others dismiss it as the practice of rigid guardians of doctrine, my friend Aaron Armstrong reminds us that Jude’s instruction is the Christian’s necessity for perseverance in the faith, the advance of the gospel, and the glory of Christ. Filled with humble boldness and delight in the gospel, Contend will equip you with a biblical framework and practical advice to winsomely and wisely stand as a witness for Christ.”

Andrew Hall, Lead Pastor, Community Bible Church, Ilderton ON

“The Internet has brought with it online shopping at the click of your fingers, e-books, blogs, and podcasts, some of which are edifying for Christians to read and grow in their faith. Sadly, a great deal of the content on the Internet in addition to what is taught through movies, television, and radio today isn’t helpful but rather harmful to the daily walk of grace of the Christian. In Aaron’s new book he argues that in order for Christians to contend well to the glory of God they must love doctrine and people. This is precisely why I’m excited about this book, because it will help a generation of Christians to rightly understand from Scripture that to contend for the Gospel doesn’t mean compromising our doctrine or our concern for people, but in fact means loving God, His Word, and His people. I encourage you to pick up this book and learn from the Word of God and Aaron’s example about what it means to contend for the faith once and for all delivered to the saints.”
