Of Tozer's many books and other writings, The Pursuit of God is his most famous and widely read. The Pursuit of God in particular has reached all the corners of the world. This book is considered a Christian classic and is still read and listened to by many faithful Christians to this day. It was written and published while he was a pastor in Chicago.
In The Pursuit of God, Tozer writes about why people pursue a relationship with God and how one can best go about doing so. Much of Tozer's doctrine can be found in this book. Tozer writes, “We need never shout across the spaces to an absent God. He is nearer than our own soul, closer than our most secret thoughts.” In chapter 1, Tozer explains that the reason one desires to pursue God is because God gave one that desire. God gives one the impulse, but one must “follow hard after him”. Tozer implores readers to strip to the “bare essentials” and present themselves before God without any efforts to impress him.
In the second chapter, Tozer uses the example of Abraham's willingness to sacrifice his only son in order to show obedience and unwavering faith. Tozer writes that one does not own anything if one follows God truly. Tozer writes, “Millions call themselves by his name, it is true, and pay some token homage to him, but a simple test will show how little he is really honored among them. Let the average man be put to the proof on the question of who or what is ABOVE, and his true position will be exposed. Let him be forced into making a choice between God and money, between God and men, between God and personal ambition, God and self, God and human love, and God will take second place every time. Those other things will be exalted above. However the man may protest, the proof is in the choice he makes day after day throughout his life.”
