Michael Horton has followed up his study of the problem with contemporary American evangelical religion, 
Christless Christianity, with this new release from Baker Books entitled The Gospel Driven Life, which can be obtained here. In this sequel Horton discusses the answer to the problem diagnosed in Christless Christianity. The problem, religion that is a mere “moralistic therapeutic deism” (an expression first coined by Christian Smith in his book Soul Searching) can only be answered with the proclamation of the gospel and a consideration of the community that is birthed by the gospel, the church. Like most of Horton’s books, this one will surely give us food for thought.
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
