The reason why we find so many dark places in the Bible is, for the most part, because there are so many dark places in our hearts.
Reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895), p. 38.
I have been young, but now am old. I have spent a whole life-time in battling against infidelity with the weapons of apologetic science; but I have become ever more and more convinced that the way to the heart does not lie through the head; and that the only way to the conversion of the head lies through a converted heart which already tastes the living fruits of the gospel.Friedrich Tholuck
The grave is a very small hillock, but we can see farther from it, when standing on it, than from the highest mountain in all the world.Friedrich Tholuck
