The Conviction to Lead by Al Mohler.
Each of Dr. Mohler's previous books has been helpful in its own way, but they have generally been repurposed sermons or blog posts and have carried the weight of mixed media. The Conviction to Lead has all the marks of an original work, oozing with wisdom and dripping with passion. This is Dr. Mohler in his most natural habitat, doing what he does best. If you are a pastor or elder, if you are an owner or CEO, if you are in any form of leadership, I am convinced that this book will transform the way you lead. I highly recommend that you read it.
The Book on Leadership by John MacArthur
Now we can say, “John MacArthur wrote the book on leadership…”
Serving Without Sinking by John Hindley
This is one for anyone who serves, but may be especially applicable to leaders.
