Hidden wisdom of the Deity, expounded in a summary of Christianity revealed in the Bible; A Discourse on Eternal Life and an analysis of the Bible Doctrine of the Kingdom of God
The Bible is the most difficult of all books to understand. First, because the Old Testament division of it contains "The Hidden Wisdom of the Deity in a Mystery," and mysteries are not self-evident; secondly, because "it is the glory of the Deity to conceal a thing," that it may be searched out by the honorable and noble minded; and thirdly, it is difficult of comprehension by the multitude, because their eyes are closed, their ears are hard of hearing, and their hearts are made gross, by the morbid influence on the "strong delusion" entailed upon them, which, as a veil upon the face of all nations, prevents the light of revelation from shining into them.
