The Need to Unlearn and Relearn
The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn and re-learn. ~ Alvin Tofler
If I could only suggest six books to help someone begin the journey of unlearning and relearning I would recommend these six. They each provide a different way to think about the church in an increasing missionary context.
The Gospel in a Pluralist Society by Lesslie Newbigin
The Church and Its Vocation by Michael Goheen
The Forgotten Ways by Alan Hirsch
Exiles by Michael Frost
The Tangible Kingdom by Hugh Halter and Matt Smay
Underground Church by Brian Sanders
If you have small groups in your church and are looking for a resource to help them move more deeply into mission, you might consider the small group curriculum and I and my friend Lance Ford created titled Missional Essentials. In fact, if you do have a group(s) use the study guide, I would be happy to join a zoom call with your group to answer questions or do a summary of the curriculum.
