The prayers I have placed on this blog are brief prayers based on the letters of the New Testament. I use the NRSV translation, and I have made them a kind of precis in prayer form. As precis, the prayers are meant to summarize the indicated chapters into a prayer that accurately reflects what the chapter teaches, although the prayers leave out many details. I hope that the original author of the letters would find them true to the spirit of the chapter on which the prayer is based. I envision using them after reading the chapter, and then praying the prayer.
Quite a few of these prayers could be used independently from reading the chapter. However, it is best to read or study the chapter, and then pray the prayer, possibly as the start of a time of prayer.
To find a prayer on a particular chapter, it is easiest to use the search function (top right hand of the page).
