The following was from the 9 Marks Twitter feed today and could be a helpful little list:
@MarkDever: Coming up: a series of 5 modern, brief books to read through with someone else in order to disciple them.
@MarkDever: 1. Greg Gilbert, What is the Gospel? Begin with the Gospel!
@MarkDever: 2. Orlando Saer, Big God. This books is good for what ales you in a number of differing ways. Helpful & enjoyable.
@MarkDever: 3. C. J. Mahaney, The Cross-Centered Life. Wonderful to see what grace looks like in real life. Well written.
@MarkDever: 4. EITHER my book What is a Healthy Church? OR (a little more advanced) Jonathan Leeman, Church Membership. Church is important!
@MarkDever: 5. Sebastian Traeger & Greg Gilbert, The Gospel at Work. Wonderfully practical at carrying the Gospel into everyday.
