The Enlightenment was an intellectual movement of the late 17th and 18th centuries that was a self-conscious move away from the Reformation's emphasis on faith and revelation. It was the mind of man that became the new standard. "My own mind is my own church," wrote Thomas Paine in his Age of Reason (Part First, 1794), which was an attack on all religion that claimed to be authoritative and Christianity in particular.

The purpose of this book (first published in 1967) is to define the nature of the opposing religious systems of thought, Christian creationism and darwinism (in its various forms). It is a call to urge Christians to stand firm for Biblical six-day creationism as a fundamental aspect of their faith in the creator. 

Genesis begins the Bible and is foundational to it. In recent years, it has become commonplace for both humanists and churchmen to sneer at anyone who takes Genesis 1-11 as historical. Yet, to believe in the myth of evolution is to accept trillions of miracles to account for our cosmos. Spontaneous generation, the development of something out of nothing, and the blind belief in the miraculous powers of chance require tremendous faith. 

The great problem in the church's interpretation of Scripture has been its ecclesiastical orientation, as though God speaks only to the church, and commands only the church. The Lord God speaks in and through His Word to the whole man, to every man, and to every area of life and thought. To assume that the Triune Creator of all things is in His word and person only relevant to the church is to deny His Lordship or sovereignty. If we turn loose the whole Word of God onto the church and the world, we shall see with joy its power and glory. This is the purpose of my brief comments.

As the last installment of R.J. Rushdoony's commentary series on the Pentateuch, it stands as one of the more dynamic expositions in the series in that it addresses God's demands upon man, family, church, and state. In short, Deuteronomy is the defining volume on theocracy. The redemptive power of Christ and the gift of the Holy Spirit are the enabling forces for a people to once again live faithful to God's covenant—and Deuteronomy provides the details for that covenant. Rushdoony's study represents a sizable deposit into securing the obedience of the church.
