After 150 years, it is time for the most important work of America's greatest revivalist to be revived. This is the unadulterated theology at the foundation of Finney's revivals. These volumes are a republication of the enlarged, unabridged 1851 London (final) edition. All subsequent editions are arbitrary abridgements almost half the size. Not only is the work before us a highly advanced moral philosophy text and logically tight systematic theology, but it is also a profoundly spiritual and devotional book. These continually interjected devotional elements make for a systematic theology as it was meant to be. Finney could not converse long on any important subject without his heart overflowing with the magnificent theme at hand in a way that vividly opens up the subject to make us see it from heaven's perspective.
