Book excerpt: This book lays out the requirements and difficulties that will come with the pursuit of holiness in our Christian lives. Ryle starts out with the way to achieve holiness and the difficulties that arise with pursuing a holy life, and then going throughout the Bible giving true examples of the cost of holiness and the rewards it brings as the Bible promises us. To often we sing and pray for such a life without being willing to undergo the necessary life changes and adjustments to get there. This book lays out what we can expect in such a journey and what God will ask of each of us to get us to the point He wants us to be.
