Daniel Musser, a Reformed Mennonite, wrote this lengthy pamphlet at the height of the American Civil War. This is one of the works that Leo Tolstoy highly praised in his Kingdom of God is Within You. Much of what Musser had to say is, indeed, praiseworthy and still valid. His major themes include a complete theology of man’s relationship to God in its pristine created state, after the fall, under the Mosaic Law, and in the power of the Holy Spirit; and the related topics of God’s immutability, His commands given in, and specifically intended for, each of these four states, and the importance of being different from the rest of the world.
