God with Logos blog writes an interesting post on prayer. He asks:
Sometimes I wish I had been raised Lutheran, or at least Christian. Maybe I would at least know how to pray, and have the discipline to be 'Christian' in all these other things. Good habits. Instead, someday, with my face deeply flushed and my voice quivering or inaudible, I'll probably have to learn them in front of my wife. That's fun to look forward to; the anticipation is already warming me
After 40+ years as a Christian, I can't say that can utter a decent prayer any better than David. I have learned to use Luther's prayers in our hymnal. I am trying to memorize the evening prayers with my kids; they are quite sufficient for me!
In the evening, when you go to bed, you are to make the sign of the holy cross and say: "Under the care of God the Father, Son and Holy Spirit. Amen."
Then, kneeling or standing, say the Apostles' Creed and the Lord's Prayer. If you wish you may recite this little prayer as well:
I give thanks to you, my heavenly Father, through Jesus Christ your dear Son, that you have graciously protected me today, and I ask you to forgive me all my sins, where I have done wrong, and graciously to protect me tonight. For into your hands I commend myself: my body, my soul, and all that is mine. Let your holy angel be with me, so that the wicked foe may have no power over me. Amen.
Then you are to go to sleep quickly and cheerfully.
