I have finished Larry Crabb's wonderful book on prayer. Maybe as you've read the Grenz, you've wondered what the Papa prayer is exactly. Basically, it is an outline with which to organize prayer that focuses much more on relating to God than getting stuff from him. Here's the outline with some quotes and key thoughts from Crabb.
Present yourself to God.
Be honest about where you are at, what you are feeling, and what you are going through. Using the mall directory with its "you are here" red dot, Crabb urges us to "Enter your red dot."
Attend to how you are thinking of God.
We have so many wrong ideas of God when we come to him in prayer. Often we think of him as a ... Smiling Buddy, Backroom Watchmaker, Preoccupied King, Vending Machine, Stern Patriarch, Kindly Grandfather, Impersonal Force, Cruel Tyrant, Moral Crusader, or Romantic Lover. Revelation 1:10-18 gives us a much different picture. We need to talk honestly with God about what we are thinking about him so that we can make sure our view of him is correct.
Purge yourself of anything that blocks your relationship with God.
Crabb writes, "In the center of your soul and mine, in the exact center, the Shekhinah glory resides – the literal, real, overwhelming presence of God." But we don't often live from that center. We live out of self-glory that results in relational sin. Crabb also says, "Right now, we’re all living with relational sin that we do not see." We must abandon ourselves to holiness, which is expressed in real love.
Approach God as the “first thing” in your life.
Crabb says, "I do not believe that we hear Papa’s voice until we discover an empty, desolate void within us that is teeming with passionate desires for fullness." Getting beyond everything else we want, we have to want God most of all. That means coming to him with an empty heart and finding that he is our Guide, Healer, King, Friend, and Donor.
These are some summary thoughts. I am still processing this book, planning on reading it again, and posting more as I consider it.
