The Hebrew Christians, to whom the Apostle wrote, were well acquainted with the laws of ceremonial purification by the blood of beasts, and birds, for by blood almost everything was purified in the service of the Temple. But it is only the blood of Christ that can purge the human conscience. In speaking of this purification, as presented in our text, let us notice—the object, the means, and the end.

I. The object of this purification is the conscience; which all the sacrificial blood shed, from the gate of Eden down to the extinction of the fire on the Jewish altar, was not sufficient to purge.

What is the conscience? An inferior judge, the representative of Jehovah, holding his court in the human soul; according to whose decision we feel either confidence, and joy in God, or condemnation, and tormenting fear. His judicial power is graduated by the degree of moral and evangelical light which has been shed upon his palace. His knowledge of the will, and character of God is the law by which he justifies, or condemns. His intelligence is the measure of his authority; and the perfection of knowledge would be the infallibility of conscience.

This faithful recorder, and deputy judge is with us through all the journey of life, and will accompany us with his register over the river Jordan, whether to Abraham’s bosom or the society of the rich man in hell. While conscience keeps a record on earth, Jehovah keeps a record in heaven; and when both books shall be opened in the final judgment, there shall be found a perfect correspondence. When temptations are presented, the understanding opposes them, but the carnal mind indulges them, and there is a contest between the judgment, and the will, and we hesitate which to obey, till the warning bell of conscience rings through the soul, and gives distinct notice of his awful recognition; and when we turn away recklessly from his faithful admonitions, we hear low mutterings of wrath stealing along the avenues, and the quick sound of writing-pens in the recording office, causing every denizen of the mental palace to tremble.

There is a good conscience, and an evil conscience. The work of both, however, is the same; consisting in keeping a true record of the actions of men, and passing sentence upon them according to their deserts. Conscience is called good, or evil only with reference to the character of its record, and its sentence. If the record is one of virtues, and the sentence one of approval, the conscience is good; if the record is one of vices, and the sentence one of condemnation, the conscience is evil.

Some have a guilty conscience, that is, a conscience that holds up to their view a black catalogue of crimes, and rings in their ears a sentence of condemnation. If you have such a conscience, you are invited to Jesus, that you may find peace to your souls. He is ever in His office, receiving all who come, and blotting out, with His own blood, the handwriting which is against them.

But some have a despairing conscience. They think that their crimes are too great to be forgiven. The registry of guilt, and the decree of death, hide from their eyes the mercy of God, and the merit of Christ. Their sins rise like mountains between them, and heaven. But let them look away to Calvary. If their sins are a thousand times more numerous than their tears, the blood of Jesus is ten thousand times more powerful than their sins. “He is able to save to the uttermost all that come unto God by Him, seeing He ever liveth to make intercession for them.”

And others have a dark, and hardened conscience. They are so deceived, that they “cry peace, and safety, when destruction is at the door.” They are “past feeling, having the conscience seared as with a hot iron.” They have sold themselves to work evil; to eat sin like bread, and drink iniquity like water. They have bribed, or gagged the recorder, and accuser within them. They will betray the just cause of the righteous, and slay the messengers of salvation, and think that they are doing God service. John the Baptist is beheaded, that Herod may keep his oath of honour. A dead fish cannot swim against the stream; but if the king’s conscience had been alive and faithful, he would have said:—“Girl, I promised to give thee thy request, even to the half of my kingdom; but thou hast requested too much; for the head of Messiah’s herald is more valuable than my whole kingdom, and all the kingdoms of the world!” But he had not the fear of God before his eyes, and the proud fool sent, and beheaded the prophet in his cell.

A good conscience is a faithful conscience, a lively conscience, a peaceful conscience, a conscience void of offence toward God, and man, resting in the shadow of the cross, and assured of an interest in His infinite merit. It is the victory of faith unfeigned, working by love, and purifying the heart. It is always found in the neighbourhood, and society of its brethren, “a broken heart and a contrite spirit;” an intense hatred of sin, and an ardent love of holiness; a spirit of fervent prayer, and supplication, and a life of scrupulous integrity, and charity; and above all, a humble confidence in the mercy of God, through the mediation of Christ. These constitute the brotherhood of Christianity; and wherever they abound, a good conscience is never lacking. They are its very element, and life; its food, its sunshine, and its vital air.

Conscience was a faithful recorder, and judge under the law, and notwithstanding the revolution which has taken place, introducing a new constitution, and a new administration, Conscience still retains his office; and when “purged from dead works to serve the living God,” is appropriately called a good conscience.
