The fundamental truths of Morals are eternal as He to whom they primarily relate, and immutable as the purposes which they subserve. But it is necessary that they should be communicated to men under different forms and according to various methods, as minds are prepared to receive them: and their application must also be regulated according to the circumstances in which men are placed. The same principle was proposed to Adam in Paradise, to Abraham in Beersheba, and to Paul when he set his face steadfastly to go to Jerusalem, knowing that bonds and afflictions awaited him there. Obedience to God was the motive proposed for abstaining from the forbidden fruit, for sacrificing an only son, and for facing suffering and death. But an intimation which was all powerful with Abraham was insufficient to secure a much less painful obedience from Adam; and the self-devotion of Paul was ennobled in all its manifold instances, by its springing, not from so many express directions, but from a principle, undeviating and perpetual in its operation. In the infancy of the race, it would have been utterly useless to reveal the grand principles of morals in any other way than that which was adopted, viz. by exhibiting their application in various instances. The Divine will was therefore made known in express directions, probably very few in number at first, and gradually increasing in number and importance, so as to enable observers, from remarking the similar tendency of several, to infer a general principle from them. All the records which we possess of the history of the race to the calling of the Israelites out of Egypt, prove this to have been the method adopted. The commands of God, and the promises and threats by which they were sanctioned, bore an analogy, in their gradual elevation, to those by which we influence an opening mind in its progress from the first manifestation of intelligence to the age when the power of conscience is recognizable. In the Mosaic system, a considerable advance was made, a direct appeal to conscience being instituted, and the gradual revelation of a moral government being provided for. Men were then taught, not what we now know, that the relation between virtue and happiness, vice and misery, is immutable (which they could not have understood,) but that in their particular case, obedience to certain laws would secure prosperity, and disobedience adversity. Such obedience, the most virtuous were incited to render, from a fear and love of God; but they could not have rendered it in any but specified cases, because, not yet being made acquainted with the principle as a principle, they could not direct its application for themselves. The case was the same with the other great principle, Benevolence, as with Piety; and, accordingly, the body of laws which was prepared for the Israelites was voluminous, and their sanctions were expressed in a copious variety of promises and threatenings, and embodied in a
