(Conscience) may fall asleep; but it will awake again: nay, though it sleep with respect to motion and operation, yet not with respect to notice and observation. So that when it does not actually call us to an account, yet it is making preparation for it. It is a witness that will not be bribed: like its Master, it accepts of no man's person. It deals impartially with the monarch and the slave: and though it may sometimes speak amiss, yet never contrary to its judgment.
It will be an eternal witness for the godly, and against the wicked. If all other witnesses were dead, yet conscience still lives, and will hereafter bear its testimony unrestrained and uncontrolled. When the sinner's mouth is stopped, the mouth of conscience will be open, and opened wider than it was before. The man without the wedding garment had nothing to say to his judge; but conscience had something to say to him: nay, it was the voice of conscience that made him speechless. This is that worm which never dies, but will be still tormenting. Its language will be, Son, remember! What bitter remorse, and severe reflections have some felt in this world! But these are nothing to what will be experienced in the next. And this, oh sinner, will be to ETERNITY ... to all ETERNITY !
Above all; let us have our hearts purged from an evil conscience, by the blood of Christ. This faculty, as well as others, is defiled, and we should seek to have it purified. If Christ speaks peace, and then conscience speaks it, we may be sure that peace is upon a solid foundation.
