If it be true that piety, justice, benevolence, wisdom, temperance, [and] fortitude, are in their own nature the most excellent and most amiable qualities of a human creature; that vice has an inherent turpitude which merits disapprobation and dislike; these truths cannot be hid from him whose understanding is infinite, whose judgment is always according to truth, and who must esteem everything according to its real value.
The Judge of all the earth, we are sure, will do right. He has given to men the faculty of perceiving the right and the wrong of conduct, as far as is necessary to our present state, and of perceiving the dignity of the one, and the demerit of the other; and surely there can be no real knowledge or real excellence in man, which is not in his Maker.
We may therefore justly conclude, that what we know in part, and see in part of right and wrong, he sees perfectly; that the moral excellence which we see and admire in some of our fellow-creatures, is a faint but true copy of that moral excellence, which is essential to his nature; and that to tread the path of virtue is the true dignity of our nature, an imitation of God, and the way to obtain his favour.
