For {4} if our heart condemn us, God is greater than our heart, and knoweth all things.

(r) If an evil conscience convicts us, much more ought the judgment of God condemn us, who knows our hearts better than we ourselves do.

People's New Testament

3:20 For if our heart condemn us. If we have a troubled conscience because we have not kept the law of love,

God is greater than our heart. God, who is greater and whose condemnation is a far more serious affair,

and knoweth all things and seeth our failure in duty.

Wesley's Notes

3:20 For if we have not this testimony, if in anything our heart, our own conscience, condemn us, much more does God, who is greater than our heart - An infinitely holier and a more impartial Judge. And knoweth all things - So that there is no hope of hiding it from him.

Jamieson-Fausset-Brown Bible Commentary

20. Luther and Bengel take this verse as consoling the believer whom his heart condemns; and who, therefore, like Peter, appeals from conscience to Him who is greater than conscience. "Lord, Thou knowest all things: thou knowest that I love Thee." Peter's conscience, though condemning him of his sin in denying the Lord, assured him of his love; but fearing the possibility, owing to his past fall, of deceiving himself, he appeals to the all-knowing God: so Paul, 1Co 4:3, 4. So if we be believers, even if our heart condemns us of sin in general, yet having the one sign of sonship, love, we may still assure our hearts (some oldest manuscripts read heart, 1Jo 3:19, as well as 1Jo 3:20), as knowing that God is greater than our heart, and knoweth all things. But thus the same Greek is translated "because" in the beginning, and "(we know) that" in the middle of the verse, and if the verse were consolatory, it probably would have been, "Because EVEN if our heart condemn us," &c. Therefore translate, "Because (rendering the reason why it has been stated in 1Jo 3:19 to be so important to 'assure our hearts before Him') if our heart condemn (Greek, 'know [aught] against us'; answering by contrast to 'we shall know that we are of the truth') us (it is) because God is greater than our heart and knoweth all things." If our heart judges us unfavorably, we may be sure that He, knowing more than our heart knows, judges us more unfavorably still [Alford]. A similar ellipsis ("it is") occurs in 1Co 14:27; 2Co 1:6; 8:23. The condemning testimony of our conscience is not alone, but is the echo of the voice of Him who is greater and knoweth all things. Our hypocrisy in loving by word and tongue, not in deed and truth, does not escape even our conscience, though weak and knowing but little, how much less God who knows all things! Still the consolatory view may be the right one. For the Greek for "we shall assure our hearts" (see on [2644]1Jo 3:19), is gain over, persuade so as to be stilled, implying that there was a previous state of self-condemnation by the heart (1Jo 3:20), which, however, is got over by the consolatory thought, "God is greater than my heart" which condemns me, and "knows all things" (Greek "ginoskei," "knows," not "kataginoskei," "condemns"), and therefore knows my love and desire to serve Him, and knows my frame so as to pity my weakness of faith. This gaining over the heart to peace is not so advanced a stage as the having CONFIDENCE towards God which flows from a heart condemning us not. The first "because" thus applies to the two alternate cases, 1Jo 3:20, 21 (giving the ground of saying, that having love we shall gain over, or assure our minds before Him, 1Jo 3:19); the second "because" applies to the first alternate alone, namely, "if our heart condemn us." When he reaches the second alternate, 1Jo 3:21, he states it independently of the former "because" which had connected it with 1Jo 3:19, inasmuch as CONFIDENCE toward God is a farther stage than persuading our hearts, though always preceded by it.

Matthew Henry's Concise Commentary

3:16-21 Here is the condescension, the miracle, the mystery of Divine love, that God would redeem the church with his own blood. Surely we should love those whom God has loved, and so loved. The Holy Spirit, grieved at selfishness, will leave the selfish heart without comfort, and full of darkness and terror. By what can it be known that a man has a true sense of the love of Christ for perishing sinners, or that the love of God has been planted in his heart by the Holy Spirit, if the love of the world and its good overcomes the feelings of compassion to a perishing brother? Every instance of this selfishness must weaken the evidences of a man's conversion; when habitual and allowed, it must decide against him. If conscience condemn us in known sin, or the neglect of known duty, God does so too. Let conscience therefore be well-informed, be heard, and diligently attended to.

Matthew Henry's Whole Bible Commentary

Verses 20-22

The apostle, having intimated that there may be, even among us, such a privilege as an assurance or sound persuasion of heart towards God, proceeds here,

I. To establish the court of conscience, and to assert the authority of it: For, if our heart condemn us, God is greater than our heart, and knoweth all things, v. 20. Our heart here is our self-reflecting judicial power, that noble excellent ability whereby we can take cognizance of ourselves, of our spirits, our dispositions, and actions, and accordingly pass a judgment upon our state towards God; and so it is the same with conscience, or the power of moral self-consciousness. This power can act as witness, judge, and executioner of judgment; it either accuses or excuses, condemns or justifies; it is set and placed in this office by God himself: the spirit of man, thus capacitated and empowered, is the candle of the Lord, a luminary lighted and set up by the Lord, searching all the inward parts of the belly, taking into scrutiny and viewing the penetralia-the private recesses and secret transactions of the inner man, Prov. 20:27. Conscience is God's vicegerent, calls the court in his name, and acts for him. The answer of a good conscience towards God, 1 Pt. 3:21. God is chief Judge of the court: If our heart condemn us God is greater than our heart, superior to our heart and conscience in power and judgment; hence the act and judgment of the court are the act and judgment of God; as, 1. If conscience condemn us, God does so too: For, if our heart condemn us, God is greater than our heart, and knoweth all things, v. 20. God is a greater witness than our conscience, and knoweth more against us than it does: he knoweth all things; he is a greater Judge than conscience; for, as he is supreme, so his judgment shall stand, and shall be fully and finally executed. This seems to be the design of another apostle when he says, For I know nothing by myself, that is, in the case wherein I am censured by some. "I am not conscious of any guile, or allowed unfaithfulness, in my stewardship and ministry. Yet I am hereby justified; it is not by my own conscience that I must ultimately stand or fall; the justification or justifying sentence of my conscience, or self-consciousness, will not determine the controversy between you and me; as you do not appeal to its sentence, so neither will you be determined by its decision; but he that judgeth me (supremely and finally judgeth me), and by whose judgment you and I must be determined, is the Lord," 1 Co. 4:4. Or, 2. If conscience acquit us, God does so too: Beloved, if our heart condemn us not, then have we confidence toward God (v. 21), then have we assurance that he accepts us now, and will acquit us in the great day of account. But, possibly, some presumptuous soul may here say, "I am glad of this; my heart does not condemn me, and therefore I may conclude God does not." As, on the contrary, upon the foregoing verse, some pious trembling soul will be ready to cry out, "God forbid! My heart or conscience condemns me, and must I then infallibly expect the condemnation of God?" But let such know that the errors of the witness are not here reckoned as the acts of the court; ignorance, error, prejudice, partiality, and presumption, may be said to be faults of the officers of the court, or of the attendants of the judge (as the mind, the will, appetite, passion, sensual disposition, or disordered brain), or of the jury, who give a false verdict, not of the judge itself; conscience-syneideµsis, is properly self-consciousness. Acts of ignorance and error are not acts of self-consciousness, but of some mistaken power; and the court of conscience is here described in its process, according to the original constitution of it by God himself, according to which process what is bound in conscience is bound in heaven; let conscience therefore be heard, be well-informed, and diligently attended to.

II. To indicate the privilege of those who have a good conscience towards God. They have interest in heaven and in the court above; their suits are heard there: And whatsoever we ask we receive of him, v. 22. It is supposed that the petitioners do not desire, or do not intend to desire, any thing that is contrary to the honour and glory of the court or to their own intended spiritual good, and then they may depend upon receiving the good things they ask for; and this supposition may well be made concerning the petitioners, or they may well be supposed to receive the good things they ask for, considering their qualification and practice: Because we keep his commandments, and do those things that are pleasing in his sight, v. 22. Obedient souls are prepared for blessings, and they have promise of audience; those who commit things displeasing to God cannot expect that he should please them in hearing and answering their prayers, Ps. 66:18; Prov. 28:9.
