The commands of the Lord are infinite principles, and in their natural and simple deductions cover all the acts of Life having any moral bearing, from the greatest to the least; and it is not the wisdom, but, the foolishness, of man, not his depth, but his shallowness, that endeavors to limit their significance and their application. We shall find that our vain attempts to do this occasion almost all our errors of judgment. "The testimony of the Lord is sure, making wise the simple," and he who is implicitly guided by it can alone walk surely; for he only has an unfailing guide in his endeavors to distinguish accurately between right and wrong. If we learn to discriminate principles wisely, our next step is to apply a similar action of the thoughts to persons; and here again it is to the laws of absolute good and evil we must look for light. We must learn to respect persons for what they are, and not for their position, their reputation, or their worldly possessions. If we are really aiming to train our own characters in accordance with the laws of absolute right, we shall be likely to respect in others the attributes we seek in our own persons. In all other efforts, there is too often envy and jealousy among those who strive; but with those who seek true excellence, whether intellectual or moral, _for its own sake_, and not from love of the world, there is always pure brotherly love; and a perpetual delight is experienced in the contemplation of excellence wherever it is found. In our estimate of the relative value of things, the same laws are called into action. If we would value them aright, we shall seek first those which aid us in improving and educating our characters, or which enlarge our powers of usefulness, and be comparatively indifferent to things which are external, and contribute only to the pleasure of the hour. True discrimination may be defined as the faculty by which we justly estimate the value and the relations of principles, of persons, and of things; and so far as we attain to it, the power of wise Thought is ultimated in Life.
