How has D.A. Carson's A Call to Spirital Reformation gone largely unnoticed? I have never heard anyone recommend it. It is a fantastic meditation on Paul's prayers and the great need of the Church today to recover a deep knowledge of God.
In chapter 1, Carson shares some thoughts about prayer gleanned over the years (get the book to read what he says about each of these):
1. Much praying is not done because we do not plan to pray.
2. Adpot practical ways to impede mental drift.
3. At various periods of your life, develop, if possible, a prayer-partner relationship.
4. Choose models--but choose them well.
5. Develop a system for your prayer lists.
6. Mingle praise, confession, and intercession; but when you intercede, try to tie as many requests as possible to Scripture.
7. If you are in any form of spiritual leadership, work at your public prayers.
8. Pray until you pray.
This last point is powerful. Carson says, "in the Western world we urgently need this advice, for many of us in our praying are like nasty little boys who ring front door bells and run away before anyone answers."
