Below are some resources that Matt recommends if you want to be InTheFight:
How Now Shall We Live (Charles Colson) A readable mesh of theology and what we are called to be and do. All of Colson's books are great but one of my favorites remains Loving God.
A Plain Account of Christian Perfection (John Wesley) Simple, profound.
Mere Christianity (C.S. Lewis) A wonderful classic. No serious Christian should go five years without reading, and re-reading. Other Lewis works to get to soon: Screwtape Letters, The Great Divorce, Chronicles of Narnia.
Bruchko (Bruce Olsen) The incredible story of how Olsen, as a teenager, flew off to the mission field and evangelized a stone age tribe. Incredible.
Called to be Holy (John Oswalt) Want to know what holiness is all about? This from one of the great biblical scholars of the evangelical world.
Hudson Taylor’s Spiritual Secret (Taylor) Missionary to China that taught how to pursue godly goals and do it with total reliance on God and the banishment of worry.
A Serious Call to a Devout and Holy Life (William Law) Easy-to-read classic that will change your perspective on a full-orbed life. A marvelous classic that penetrates through the phoniness
Preaching in the Spirit (Dennis Kinlaw) Get it whether you are a preacher or not. And get everything else Kinlaw has written. A modern communicator without peer.
Compassionate Conservatism (Marvin Olasky) Tons of examples here of how compassionate conservatism lives, and usually without any help from the government.
Celebration of Discipline (Richard Foster) A modern day spiritual formation classic. Covers both corporate and personal disciplines.
The Hour That Changes the World (Dick Eastman) Teaches a twelve step method of prayer that is refreshing, uplifting and very doable.
Scandal of the Evangelical Conscience (Ron Sider) How low has the "evangelical" crowd sunk? Low...but there is hope.
John Wesley’s Sermon #98 ("Google" it) Compassion is biblically necessary. And it is of the "hands-on" variety, not simply sitting on boards or giving money.
Pursuit of God (A.W. Tozer) Anything you read of Tozer will draw you deeper in Christ; this is a good start.
Heavenly Man (Brother Yun) Think you know a little bit about hungering and thirsting for righteousness and getting persecuted for it? No, you don’t.
The Master Plan of Evangelism (Robert Coleman) If you make disciples by sitting around and talking, then your disciples will in all likelihood sit around and talk. Jesus had a better methodology.
Tragedy of American Compassion (Marvin Olasky) How to take compassion seriously. American once did. No longer…but we can begin again.
