"You will of course, read other books besides the Bible; but beware lest these diminish your power. Perhaps in no department of literature are works of vigorous and original thought rarer than in theology. No profession is so overwhelmed with common- place, weak, worthless books as our ours. No text has been so obscured and oppressed by undiscerning commentators as the Bible. In theology, as in all branches of knowledge, confine yourself very much to the works of men who have written not from tradition, or imitation, but from consciousness, experience, reflection, and research; and study these, that your own faculties may be roused to a kindred energy." 

  I might add that my blog is an attempt to gather this kind of Christian thought.
