Matthew 5:23-24
23. Therefore—to apply the foregoing, and show its paramount importance.
if thou bring thy gift to the altar, and there rememberest that thy brother hath aught—of just complaint "against thee."24. Leave there thy gift before the altar, and go thy way; first be reconciled to thy brother—The meaning evidently is—not, "dismiss from thine own breast all ill feeling," but "get thy brother to dismiss from his mind all grudge against thee."
and then come and offer thy gift—"The picture," says THOLUCK, "is drawn from life. It transports us to the moment when the Israelite, having brought his sacrifice to the court of the Israelites, awaited the instant when the priest would approach to receive it at his hands. He waits with his gift at the rails which separate the place where he stands from the court of the priests, into which his offering will presently be taken, there to be slain by the priest, and by him presented upon the altar of sacrifice." It is at this solemn moment, when about to cast himself upon divine mercy, and seek in his offering a seal of divine forgiveness, that the offerer is supposed, all at once, to remember that some brother has a just cause of complaint against him through breach of this commandment in one or other of the ways just indicated. What then? Is he to say, As soon as I have offered this gift I will go straight to my brother, and make it up with him? Nay; but before another step is taken—even before the offering is presented—this reconciliation is to be sought, though the gift have to be left unoffered before the altar. The converse of the truth here taught is very strikingly expressed in Mr 11:25, 26: "And when ye stand praying (in the very act), forgive, if ye have aught (of just complaint) against any; that your Father also which is in heaven may forgive you your trespasses. But if ye do not forgive, neither will your Father which is in heaven forgive you," &c. Hence the beautiful practice of the early Church, to see that all differences amongst brethren and sisters in Christ were made up, in the spirit of love, before going to the Holy Communion; and the Church of England has a rubrical direction to this effect in her Communion service. Certainly, if this be the highest act of worship on earth, such reconciliation though obligatory on all other occasions of worship—must be peculiarly so then.Matthew 6:15
15. But if ye forgive not, &c.—See on Mt 6:12.
Fasting (Mt 6:16-18). Having concluded His supplementary directions on the subject of prayer with this Divine Pattern, our Lord now returns to the subject of Unostentatiousness in our deeds of righteousness, in order to give one more illustration of it, in the matter of fasting.
James 2:13
13. The converse of, "Blessed are the merciful, for they shall obtain mercy" (Mt 5:7). Translate, "The judgment (which is coming on all of us) shall be without mercy to him who hath showed no mercy." It shall be such toward every one as every one shall have been [BENGEL]. "Mercy" here corresponds to "love," Jas 2:8.
mercy rejoiceth against judgment—Mercy, so far from fearing judgment in the case of its followers, actually glorifieth against it, knowing that it cannot condemn them. Not that their mercy is the ground of their acquittal, but the mercy of God in Christ towards them, producing mercy on their part towards their fellow men, makes them to triumph over judgment, which all in themselves otherwise deserve.
