So in Life, if we compare our own lives with the lives of our neighbors, we shall be envious and jealous, or else self-conceited and proud; and our efforts will probably soon slacken, and then cease; and then we shall begin to go down hill, at the very moment, perhaps, when we are taking credit to ourselves for our rapid, or our finished, ascent. If, on the other hand, we compare our lives with that absolute perfection which the Lord sets before us as our model, we shall incur the danger of none of these vices; and though the greatness of our task may well cause us to "work in fear and trembling," we shall ever be cheered by the consciousness that "the Lord worketh within us both to will and to do." When our characters take form in external Life, Thought must give us discrimination, Imagination must give us courage, and Affection must give us earnestness; then our external nature will be the transparent medium through which the internal nature will shine, with a lustre undiminished by the opacity which is sure to dim its radiance when dulness, fearfulness, or indolence inheres with the external nature; for then it forms a husk to hide, instead of a medium to display, the workings of the inner being. The powers that have been treated of in the preceding essays are sometimes found to work well so long as they work upon abstractions; but so soon as they are required to work upon the daily Life, they fail of reaching so high a point of excellence as we think we had reason to anticipate. This results from the want of either discrimination, courage, or earnestness; and the inner nature cannot be thoroughly trained until these faculties are so developed by its life-giving power, that their weakness ceases to interfere with its movements when it seeks to manifest itself in external Life.
