It is a good thing to let prayer be the first business of the morning and the last at night. Guard yourself carefully against those false, deluding ideas which tell you, “Wait a little while. I will pray in an hour; first I must attend to this or that.” Such thoughts get you away from prayer into other affairs which so hold your attention and involve you that nothing comes of prayer for that day.
When your heart has been warmed by such recitation to yourself (of the Ten Commandments, the words of Christ, etc.) and is intent upon the matter, kneel or stand with your hands folded and your eyes toward heaven and speak or think as briefly as you can:
O Heavenly Father, dear God, I am a poor unworthy sinner. I do not deserve to raise my eyes or hands toward thee or to pray. But because thou hast commanded us all to pray and hast promised to hear us and through thy dear Son Jesus Christ hast taught us both how and what to pray, I come to thee in obedience to thy word, trusting in thy gracious promise. I pray in the name of my Lord Jesus Christ together with all thy saints and Christians on earth as he has taught us: Our Father who art in Heaven, hallowed be Thy Name. Thy Kingdom come. Thy Will be done on earth as it is in Heaven. Give us this day our daily bread. And forgive us our debts, as we forgive our debtors. And lead us not into temptation but deliver us from evil. For Thine is the Kingdom, and the Power, and the Glory, forever. Amen.
