10. Again: the Earth is a scene of Moral Trial. Man is subject to a Moral Law; and this Moral Law is a Law of which God is the Legislator. It is a law which man has the power of discovering, by the use of the faculties which God has given him. By considering the nature and consequences of actions, man is able to discern, in a great measure, what is right and what is wrong;--what he ought and what he ought not to do;--what his duty and virtue, what his crime and vice. Man has a Law on such subjects, written on his heart, as the Apostle Paul says. He has a conscience which accuses or excuses him; and thus, recognizes his acts as worthy of condemnation or approval. And thus, man is, and knows himself to be, the subject of Divine Law, commanding and prohibiting; and is here, in a state of probation, as to how far he will obey or disobey this Law. He has impulses, springs of action, which urge him to the violation of this Law. Appetite, Desire, Anger, Lust, Greediness, Envy, Malice, impel him to courses which are vicious. But these impulses he is capable of resisting and controlling;--of avoiding the vices and practising the opposite virtues;--and of rising from one stage of Virtue to another, by a gradual and successive purification and elevation of the desires, affections and habits, in a degree, so far as we know, without limit. 11. Now in considering the bearing of this view upon our original subject, we have, in the first place, to make this remark: that the existence of a body of creatures, capable of such a Law, of such a Trial, and of such an Elevation as this, is, according to all that we can conceive, an object infinitely more worthy of the exertion of the Divine Power and Wisdom, in the Creation of the universe, than any number of planets occupied by creatures having no such lot, no such law, no such capacities, and no such responsibilities. However imperfectly the moral law be obeyed; however ill the greater part of mankind may respond to the appointment which places them here in a state of moral probation; however few those may be who use the capacities and means of their moral purification and elevation;--still, that there is such a plan in the creation, and that any respond to its appointments,--is really a view of the Universe which we can conceive to be suitable to the nature of God, because we can approve of it, in virtue of the moral nature which He has given us. One school of moral discipline, one theatre of moral action, one arena of moral contests for the highest prizes, is a sufficient centre for innumerable hosts of stars and planets, globes of fire and earth, water and air, whether or not tenanted by corals and madrepores, fishes and creeping things. So great and majestic are those names of _Right_ and _Good_, _Duty_ and _Virtue_, that all mere material or animal existence is worthless in the comparison.
