The spiritual growth of mankind has proceeded through three great stages. Each of these has been marked by the evolution of one predominating element, or salient principle of religious action. On examination, we shall be able to discover an impressive correspondence between these successive epochs in the history of humanity at large, and the process of life in a well-disciplined, Christianized individual. This analogy is so thickly set with points of interest, as well as so fruitful of practical suggestions touching right religious ideas, and right living, that I shall let it fix the form, and be the subject of the discourse. That subject is: _The threefold discipline of our spiritual experience, as compared with the threefold order in the expanding nurture of the human family_. The three Biblical dispensations are types of three great principles of conduct, or rather three schools of religious culture, under which we must pass as persons, just as the race has passed in history, before we can be built up into the symmetrical stature of a Christian maturity. I. First, was the dispensation of natural religious feeling. The race was in childhood. It acted from impulse. It obeyed no written code of moral regulations, but, so far as its life was right, it either followed some free religious instincts, or else depended on direct intimations from the Deity, directing or forbidding each specific deed. The man chosen as the representative of this period was Abraham. The record of it is the book of Genesis. That writing is the first grand chapter in the biography of man; and its very literary structure—so dramatic in contents, and so lyrical in expression, so careless of the rules of art, so abounding in personal details, and graphic groupings of incident; so like a child’s story in its sublime simplicity—answers to the spontaneous period it pictures. “The patriarchal age” we call it. The term itself intimates rude, unorganized politics; the head of each family being the legislator for his tribe. But, in the absence of systematic statutes, every man, by a liberty so large as to burst often into license, was likely to do very much what was right in his own eyes. If he had strong passions, he would be a sensualist, like Shechem, or a petty tyrant, like Laban. If he were constitutionally gentle, he would be an inoffensive shepherd, like Lot. Such were the first two brothers. Cain’s jealousy made him a murderer; Abel was peaceable, kept sheep, and the only voice he lifted up against outrage, was when his blood cried from the ground. Some of these nomadic people, having devout temperaments, “called upon the name of the Lord,” we are told, like Enoch and Noah. Others were bloated giants, mighty men in animal propensities, gross and licentious, given to promiscuous marriages; so that presently God saw that the wickedness was so great, and the imaginations of men’s hearts were so evil, that he must wash the unclean earth with a deluge.
