The Judicial Function of Conscience
1 John 3:19-22
And hereby we know that we are of the truth, and shall assure our hearts before him.…


And hereby we know that we are of the truth, etc. Our text suggests the following observations.

I. THAT CONSCIENCE EXERCISES A. JUDICIAL FUNCTION IN MAN. By "our heart" in the text St. John means, as Alford says, "the heart as the seat of the conscience, giving rise there to peace or to terror, according as it is at rest or in disquietude.... The heart here is the inward judge of the man." Many are the definitions of "conscience." "Man's conscience is the oracle of God." "Conscience is God's monitor in the soul of man." "The sense of right." "God's vicegerent in the soul." Dr. Whewell: "Conscience is the reason employed about questions of right and wrong, and accompanied with the sentiments of approbation and condemnation." The function of conscience is not to give the Law unto us, but to pronounce whether we have kept the Law or not. "It is the great business of conscience," says Archbishop Leighton, "to sit, and examine, and judge within; to hold courts in the soul; and it is of continual necessity that it be so." It is most important that we bear in mind that for us conscience is not an infallible guide in the ethics of conduct. Some of the darkest crimes that were ever committed have been sanctioned by conscience. Saul of Tarsus was conscientious in his fierce persecution of the early Christians. "I verily thought with myself, that I ought to do many things contrary to the Name of Jesus of Nazareth" (Acts 26:9-11). And in subsequent ages many a persecutor has resembled him in this respect while perpetrating the most revolting cruelties. That the judgment of conscience may invariably be true and perfect it must needs be regulated by the revealed will of God, and be inspired by the Holy Spirit. We should take the will of God in Christ Jesus for our law; and then let conscience, quickened by the Spirit of God, exercise its judicial function in condemning or approving us in our relation to that law.

II. THAT WHEN, IN THE EXERCISE OF ITS JUDICIAL FUNCTION, CONSCIENCE CONDEMNS US, MUCH MORE ARE WE CONDEMNED BY THE HOLY GOD. "For if our heart condemn us, God is greater than our heart, and knoweth all things." To my mind these words suggest two important considerations.

1. Our conscience is an imperfect judge, but God is absolutely and infinitely holy. Conscience has undoubtedly suffered by reason of human sin. Its judgments arc not always of the most exalted character. As a judge it is sometimes partial. Sometimes it allows what if it were perfectly pure it must condemn. But "God is greater than our heart." His righteousness is perfect. Sin in every form is utterly abhorrent to him. His holiness is without the slightest spot or the faintest shadow. The greatness of his mercy towards the sinner does not lead him to excuse any sin. If our heart condemn us, how much more does be? If our conscience, which is but a faint and imperfect echo of his voice, condemn us. bow much more does he?

2. Conscience may not take cognizance of every sin, but God "knoweth all things." There are sins which escape the vigilance of conscience. A man's secret sins may be of three classes:

(1) those which are unknown to his fellow-men, but known to himself;

(2) those which are not recognized as sins by himself, but are so viewed by his fellow-men; and

(3) those which are not regarded as sins either by himself or his fellow-men. But no sins whatever are hidden from God. "His eyes are upon the ways of man, and he seeth all his goings. There is no darkness," etc. (Job 34:21, 22); "He hath set our iniquities before him, our secret sins in the light of his countenance." If, then, our conscience with its imperfect information, condemn us, how much more must he who "knoweth all things"! "If conscience be as a thousand witnesses," says Dr. Arrowsmith, "the all-seeing God is as a thousand consciences."

III. THAT WHEN, IN THE EXERCISE OF ITS JUDICIAL FUNCTION, CONSCIENCE DOES NOT CONDEMN US, WE REGARD GOD WITH INSPIRING CONFIDENCE. "Beloved, if our heart condemn us not, then have we confidence towards God." Notice:

1. Confidence in God as to its nature. "Hereby we know that we are of the truth, and shall assure our heart before him." It is the firm persuasion, the assurance, of the heart that we are his children, and that we may look to him to be to us and to do for us all that he has promised to be to and to do for his children. Or, if we view it as indicated by the twenty-first verse, it is the confidence that he does not condemn us, but that he accepts us now and will own us in the great day. How precious is this assurance!

2. Confidence in God springing from the exercise of holy love and the approbation of conscience. "Hereby shall we know that we are of the truth, and shall assure our hearts before him." The "hereby" refers to what has gone before. He who loves neither in word nor with the tongue, but in deed and truth, may know that he is "of the truth," etc. "We know that we have passed out of death into life, because we love the brethren;" "He that loveth his brother abideth in the light." Again, St. John speaks of this assurance towards God as springing from an approving conscience (verse 21). Apart from the approbation of the inward monitor, we cannot look Godward with confidence or with joy.

3. Confidence in God inspiring the conviction that he will answer our prayers to him. "And whatsoever we ask, we receive of him, because we keep his commandments, and do the things that are pleasing in his sight." The keeping of his commandments is not meritorious; it does not give us a claim upon him for the blessings which we ask in prayer; but it is an indication of character which shows that the suppliant will ask only what is in accordance with his will. That we "do the things that are pleasing in his sight" is a guarantee that we shall desire only those things which he will be pleased to bestow upon us (cf. 1 John 5:14, 15; Psalm 37:4). Having the assurance that we are his children and endeavouring to please him, we are persuaded that the wise and gracious Father will answer our prayers to him. - W.J.
