In twenty sermons, William G. T. Shedd discusses topics of spiritual life and Christian theology; God and His infinite knowledge of the world and of mankind, and the role of sin.

A great compendium of Shedd's finest preaching, this book was published in an attempt to express the divine truth of God. Unabashed about the lecture's focus on sin and the almighty power of the Lord, the words here attempt to explain the core truths of the Bible. Christ's life and purpose, the events and circumstances surrounding His life, and the ineffable tenets which all believers must heed - these topics stand at the core of what W. G. T. Shedd wishes to express.

The author is wary of attaining a balance in these writings, musing that it is all too easy for a learned man of God to slip too greatly toward severity. Another peril is omitting crucial analyses, or delving insufficiently into topics: from the outset, Shedd makes clear that he wishes to give readers his complete understanding of sin in Christian theology.
