A typical case of such unbelief begins when young men are brought up as nominal Christians. Their parents take them to church as children and there they become acquainted with those passages of the Bible used in the service. If their parents still keep some of the old habits, they may even be taught in the catechism. But they go off into the world, yield to youthful temptations, neglect to look at their Bible, and they do not develop their religious duties. They do not even try to reflect, study, or mature in the thoughts that they once might have had as children. They may even travel abroad, relax still further their religious habits, and tend to read only about those controversial issues of religion. Attending church occasionally, these occasional incidents more often offend such youth than strengthen them. Perhaps they are tempted to be morally superior to those they think are superstitious. Or the poor examples of some professing Christians disgust them. Or else they stumble because of the absurdities of others who see they are equally ignorant to themselves. At any rate, they gradually begin to doubt the reality of Christianity. A confused sense of relief that it is all untrue settles within them. Impressions deepen, reinforced by fresh arguments. At length they are convinced of their doubts in a broad sweep over the whole realm of religion. This may not be universally so, but it may be termed the natural history of skepticism. It is the experience of those who have watched the progress of unbelief in those they care about. It is confirmed by the written lines of some of the most eminent unbelievers. We find that they once gave a sort of implicit, inherited assent to the truth of Christianity and were considered believers. How then did they become skeptics? Reason, thought, and inquiry have little to do with it. Having lived for many years careless and irreligious lives, they eventually matured in their faithlessness—not by force of irreligious strength but by lapse of time. This is generally the offspring of prejudice, and its success is the result of moral depravity. Unbelief is not so much the result of a studious and controversial age as it is one of moral decline. It disperses itself in proportion as the general morals decline. People embrace it with less apprehension when all around are doing the same thing.
