Public prayer is a difficult thing, especially for one who is leading worship.  It takes a lot of work to do it well.  And perhaps the biggest struggle for many is that it also takes a vibrant prayer life at home.  I just bought a copy of The Pastor in Prayer which is a collection of pastoral prayers Charles Spurgeon gave during worship services.  It’s quite humbling to hear how this man devoted to prayer was able to lead his flock in worship.  I purchased the book on a recommendation of Carl Trueman’s and I’d like to pass the recommendation on myself.  Get a copy and while you’re at it, get the The Valley of Vision to read at home if you don’t have one already.
Camden, you will also want to make our readers aware of Samuel Miller’s Thought’s on Public Prayer.
It’s old, but it is useful:
