It can sometimes be helpful to have a book of written prayers that you can use so that you can address issues for which you cannot seem to find the words or so that you can pray more smoothly with others. The books below offer a variety of styles because the ways people express themselves in prayer can be very different, even when they address the same subject.
Lutheran Book of Prayer, 5th ed. (CPH, 2005) contains prayers for many situations in which Lutherans find themselves. It has been a staple in numerous Lutheran families for many years.

My Prayer Book (CPH, 2021) also contains prayers for the many times when Lutherans desire to pray, but the prayers are styled differently than those in the Lutheran Book of Prayer.
