Improving your serve is one of the best teaching studies that I have ever read. It gave me a perspective of what it truly is to be a Servant of God, instead of someone going through motions claiming to serve. As a children's pastor, I am always the leader, the boss; As a servant of God, I am to humble myself before even the smallest of His children.
I have made this book required reading for every ministry leader under my umbrella. It has changed my life, my ministry, and my vision of ministry. It will change yours as well.
This is an excellent book talking about how to live happily every day independent of the world promoting SELF exalted messages. The long lasting happiness described in this book is to live willingly and humbly for God's glory.
