"Prayer is made vigorous by petitioning; urgent by supplication; by thanksgiving, pleasing and acceptable." (p.133)
I do find it easy to muddy the waters of some things that have simple explanations. Ina n effort to go "deeper" I am sometimes merely confusing, even to myself. Prayer is a subject that easily goes awry in this way.
Prayer is asking. Luther has some straightforward advice about how to ask in a good way so my prayer will reach God and so God can reach me.
"Petition is stating what we have at heart." Luther says to bring life to prayer, my prayers must be specific and personal, addressing my real concerns and worries. I find a great help to petition is "talking normally" with God, avoiding ideas and hopes that are "too lofty" and sticking with present needs and desires. The normal talk seems to keep things real for me.
"In supplication we strengthen prayer and make it effective by a certain form of persuasion." To aid in supplication, I find two things helpful. One is a regular diet of Psalms to remind me of the many facets of God's kindness, love, mercy, and power. Another is actual positioning of my body. Kneeling, opening or closing eyes, or lifting my hands can greatly enhance this supplication that Luther speaks of.
I do not think that supplication makes God do anything as if words and motions were some sort of incantation. Rather I find that using all my mind and all my strength in loving God reflects the sort of faith I have in him as a personally interactive God, having conversations with me, rather than just receiving my requests like an order at a fast food restaurant. I try to give prayers as I think they are received by him, with thoughtfulness and passion, a divine urgency.
Finally, thanksgiving. When thanksgiving surrounds my prayer, I feel peace about what God is doing and will do about my prayer. For thanksgiving, I will often recall how God has been faithful to me, someone close to me, or even to someone in the Bible. His faithfulness in the past enables me to thank him in the present even when I do not yet have what I have asked for.
Thanksgiving makes all requests pleasing. A request from a grateful child contrasts from a spoiled child in its thanksgiving. When gratitude is missing, I find that a new request is made before the last provision has even been enjoyed. The eye is on getting more, rather than on enjoying what has been given. This has its mirror in my prayers as well. I try to stuff something else in my mouth while I'm still chewing on what God gave me before.
So thankfulness works best for me when I pause and think of how God is good. Reflection is good fuel for thanksgiving. Just a few moments of silence before I begin to ask for things can really frame my whole prayer into love and adoration instead or whining and complaining.
Lord, would that I were more simple in my heart before you. My thoughts get in the way sometimes. They are important, I know, but not as important as just coming to you when I need something, knowing that you are dying to help me in any way you can. Let my thoughts bring me closer to you, so a childlike heart will be natural for me. Amen.
Really just asking more would help me a lot. I think a lot, praise a lot, but forget to ask for much. To this Luther writes, "If you do not know or recognize your needs, you are in the worst possible place. The greatest trouble we can ever know is thinking that we have no trouble for we have become hardened and insensible to what is inside us." (p.134)
