The second class of persons who need wisdom in the control of their moods is that large class whose unfortunate circumstances make it impossible for them to avoid constantly overdoing and overdrawing upon their nervous energies, and who therefore are always exhausted and worn out. Poor souls, who labor daily under a burden too heavy for them, and whose fretfulness and impatience are looked upon with sorrow, not anger, by pitying angels. Poor mothers, with families of little children clinging round them, and a baby that never lets them sleep; hard-working men, whose utmost toil, day and night, scarcely keeps the wolf from the door; and all the hard-laboring, heavy-laden, on whom the burdens of life press far beyond their strength. There are but two things we know of for these,--two only remedies for the irritation that comes of these exhaustions; the habit of silence towards men, and of speech towards God. The heart must utter itself or burst; but let it learn to commune constantly and intimately with One always present and always sympathizing. This is the great, the only safeguard against fretfulness and complaint. Thus and thus only can peace spring out of confusion, and the breaking chords of an overtaxed nature be strung anew to a celestial harmony. III. REPRESSION. I am going now to write on another cause of family unhappiness, more subtile than either of those before enumerated. In the General Confession of the Church, we poor mortals all unite in saying two things: “We have left undone those things which we ought to have done, and we have done those things which we ought not to have done.” These two heads exhaust the subject of human frailty. It is the things left undone which we ought to have done, the things left unsaid which we ought to have said, that constitute the subject I am now to treat of. I remember my school-day speculations over an old “Chemistry” I used to study as a textbook, which informed me that a substance called Caloric exists in all bodies. In some it exists in a latent state: it is there, but it affects neither the senses nor the thermometer. Certain causes develop it, when it raises the mercury and warms the hands. I remember the awe and wonder with which, even then, I reflected on the vast amount of blind, deaf, and dumb comfort which Nature had thus stowed away. How mysterious it seemed to me that poor families every winter should be shivering, freezing, and catching cold, when Nature had all this latent caloric locked up in her store-closet,--when it was all around them, in everything they touched and handled! In the spiritual world there is an exact analogy to this. There is a great life-giving, warming power called Love, which exists in human hearts dumb and unseen, but which has no real life, no warming power, till set free by expression.
