Prayer- one of those areas in which we all know we fall short. Yet there is opportunity for joyful communion with God here as we battle on in the Christian life. Prayer is amazingly simple and can be incredibly sweet and enriching. It has been said that prayer is like breathing for the Christian. If all this is true may we as individuals and as a body be continually growing in this discipline.
Here are some recommended resources on prayer-
An Intimate Hour with God- by Jim Elliff- an good article on prayer with some helpful suggestions.
A Call to Prayer by J.C.Ryle- a classic booklet on prayer showing the necessity of prayer.
How to Pray for a Soul- a short but very helpful article by John Piper
Big, Sweeping, but not Insipid Prayers- an article by John Piper
There many other resources available from John Piper through Desiring God which you can find here.
In the realm of books it is difficult to beat D.A. Carsons book A Call to Spiritual Reformation- available at our resource table.
I have probably missed a good number of solid resources but I think you will find this list edifying.
As always, there is nothing better than Scripture itself- God knows what He is talking about. In particular, the Psalms, Matthew 6:5-15, and numerous other NT passages on prayer are helpful.
