Does not all this show that there is a deep and hidden fountain of evil within our hearts which is restrained by external influences, by checks and barriers with which God has kindly surrounded us? and if these were taken away, it would break out into something far worse than now appears. How much there is of evil under the smooth surface of refined society! How many thoughts of sin pass to and fro in the heart while the countenance seems pure and calm! Who ever looked into the interior depths of our most moral community, and saw all the secret sins and pollutions which are hidden there? Every now and then there occurs in the midst of the most refined classes some startling revelation of long-concealed wickedness which makes men look each other in the face and draw a long breath, as though they should say, “Which of us will next fall?” So in the midst of a fruitful country, of lakes, and valleys, and vine-clad hills, the earth will sometimes open, and a river of melted lava pour forth, desolating all around. We hear of this with wonder, and do not think that right beneath our own feet, a few miles down, under these smooth fields and gentle plains, that same fiery ocean is rolling its red billows. God has laid his hand upon our heart, and restrains its lawless passions as he restrains the tornadoes, and earthquakes, and volcanic fires; else they might easily hurry us to swift destruction. Still, if this were all, no radical change might be necessary. It might be enough that by effort, and self-discipline, and direction of the thoughts, we gradually overcome our evil habits and tendencies; but when we resolve to do so, and make the effort, we meet with an unexpected resistance. “The spirit is willing, but the flesh is weak.” “I find a law in my members warring against the law of my mind, and bringing me into captivity to the law of sin in my members.” The Church has long asserted the doctrine of an hereditary depravity; and we have seen that there is more truth in it than we have sometimes supposed. It is not total, but it is real. Besides the sins of our own committing, there are the sins which our ancestors have committed, which have made themselves part of our bone and flesh. We are not exactly balanced in our natural state; there is a preponderating tendency towards evil in one or another direction.
