Every act of our lives affects others for good or evil. Our influence is tending upward or downward; it is felt, acted upon, and to a greater or less degree reproduced by others. If by our example we aid others in the development of good principles, we give them power to do good. In their turn they exert the same beneficial influence upon others, and thus hundreds and thousands are affected by our unconscious influence. If we by acts strengthen or force into activity the evil powers possessed by those around us, we share their sin and will have to render an account for the good we might have done them and did not do, because we made not God our strength, our guide, our counselor.—Testimonies for the Church 2:133 (1868).
