The following is an example of a John Calvin prayer to open one of the week-day services in Geneva:
We call upon our good God, praying that He may be pleased to regard us His poor servants with His fatherly mercy, not imputing to us our many faults and sins, by which we never cease daily to provoke His wrath against us. And since we are not worthy to appear before His holy majesty, may He please to receive us in the name of His beloved Son our Lord Jesus Christ, accepting the merit of His passion and death in recompense for all our faults, because in our own works we cannot stand before His face. May He please to enlighten us by His Holy Spirit in true understanding of His holy word, enabling us to handle it faithfully, and to receive it in true fear and humility. May we be taught by it to put our full confidence in Him, that we may serve and honor Him as is fitting, to glorify His holy name with our whole life and to edify our neighbors by our good example. We ask all these thing, as our good Savior and Redeemer Jesus Christ taught us, saying: Our Father who art in heaven, . . .
I read this and wonder how often prayers such as these are said today. Are there elements you find therein that you do not find common today? Or do you believe that is this kind of prayer is common? Your input is welcome.
