Biography
Filling Up the Afflictions of Christ: The Cost of Bringing the Gospel to the Nations in the Lives of William Tyndale, Adoniram Judson, and John Paton
by
John Piper
The stories of these three faithful men are not just inspiring, but model to us a courage, steadfastness, and willingness to endure suffering that all of them could have gotten out of. But their focus on Christ and His worthiness kept each of them able to withstand the trials, losses, and hardships that came with their service to the Lord Jesus. Piper does a wonderful job of condensing these giants of the faith so we get to glean critical lessons from their costly lives.
To the Golden Shore
by
Courtney Anderson
Let Anderson transport you to a world of New England Christianity, life in India, and the hardships in pioneering missionary work in Burma, that is now long gone. Anderson tells a story of intense focus, setback after setback, and courage that continues to make you shake your head all throughout this book. Anderson does not write to shock, his ‘just the facts’ style is not meant to play on your emotions, but this well-researched story on the life of Adoniram Judson will keep you spellbound, challenge your own faith and remind us how far we have slipped from such hold-back-nothing commitment to our Lord Jesus.

The E-Myth Revisited: Why Most Small Businesses Don’t Work and What to Do About It
by
Michael E. Gerber
Most of our graduates plan to work in countries where business will be an important part of their daily activity and their connection to the community around them. We provide an introduction to business development as part of our Identity, Access & Business module, and we are using Gerber’s classic as our textbook. It’s a very helpful book because (1) it’s rooted in broad experience and the real-life challenges of developing a business, (2) it’s very practical, and (3) its goal is to help business owners develop their business to the point where it can be managed by others, freeing the owner to reduce the amount of time that his hands-on supervision

Effective Discipling in Muslim Communities
by
Don Little
Don offers a clear alternative to some of the trendy, non-serious methods that are being advanced. His reminder that a serious conversion experience is critical (based off of understanding the gospel) is rare in our day of surface level presentations of ‘the gospel’. He also shows how important that the open door life of the ‘
Planting Churches in Muslim Cities: A Team Approach
by
Greg Livingston
Livingstone speaks of the character of the church planter with an awareness that few have, and few have written about. The focus is on those heading into a Muslim context and what it takes to plant churches there. Most of those commitments and understandings will benefit those going to Hindu, Buddhist and Animistic cultures also. Although the book is not long on
Seeking Allah, Finding Jesus: A Devout Muslim Encounters Christianity
by
Duane Elmer
Although not written from a cross-cultural, cross-language situation Qureshi tells the story of his own conversion from Islam while done in his University years. How God used his friend David as a faithful witness is a model for all who would seek to work with Muslims here, or cross-culturally. How David took Islam seriously, addressed questions over the course of years, befriended Quereshi in very tangible ways is real ‘how to’ for Christians in interacting with devout followers of other religions.
