Conscience is a most powerful part of our natural constitution. It cannot save our souls. It never leads a man to Christ. It is often blind, and ignorant, and misdirected. Yet conscience often raises a mighty testimony against sin in the sinner’s heart, and makes him feel that “it is an evil and a bitter thing” to depart from God. Young people ought especially to remember this, and, remembering it, to take heed to their ways. Let them not flatter themselves that all is right, when their sins are past, and done, and forgotten by the world. Let them know that conscience can bring up each sin before the eyes of their minds, and make it bite like a serpent.
