Spurgeon said John Boys "was one of the richest writers" being "all essence.' This volume contains Boys's exposition of Scripture passages used in the services of Morning and Evening Prayer and Holy Communion in the Book of Common Prayer, as well as his writings on the Psalms, expositions on the epistles and gospels, and comments on the Apostle's Creed, the Lord's Prayer, and the Ten Commandments. This work makes it clear that Boys had the gift of making complex doctrine plain and practical.'"
