For where two or three are gathered together in my name, there am I in the midst of them.

People's New Testament

18:20 In my name. As followers of Christ.

Wesley's Notes

18:20 Where two or three are gathered together in my name - That is, to worship me. I am in the midst of them - By my Spirit, to quicken their prayers, guide their counsels, and answer their petitions.

Jamieson-Fausset-Brown Bible Commentary

20. For where two or three are gathered together in my name-or "unto my name."

there am I in the midst of them-On this passage-so full of sublime encouragement to Christian union in action and prayer-observe, first, the connection in which it stands. Our Lord had been speaking of church meetings before which the obstinate perversity of a brother was in the last resort to be brought, and whose decision was to be final-such honor does the Lord of the Church put upon its lawful assemblies. But not these assemblies only does He deign to countenance and honor. For even two uniting to bring any matter before Him shall find that they are not alone, for My Father is with them, says Jesus. Next, observe the premium here put upon union in prayer. As this cannot exist with fewer than two, so by letting it down so low as that number, He gives the utmost conceivable encouragement to union in this exercise. But what kind of union? Not an agreement merely to pray in concert, but to pray for some definite thing. "As touching anything which they shall ask," says our Lord-anything they shall agree to ask in concert. At the same time, it is plain He had certain things at that moment in His eye, as most fitting and needful subjects for such concerted prayer. The Twelve had been "falling out by the way" about the miserable question of precedence in their Master's kingdom, and this, as it stirred their corruptions, had given rise-or at least was in danger of giving rise-to "offenses" perilous to their souls. The Lord Himself had been directing them how to deal with one another about such matters. "But now shows He unto them a more excellent way." Let them bring all such matters-yea, and everything whatsoever by which either their own loving relationship to each other, or the good of His kingdom at large, might be affected-to their Father in heaven; and if they be but agreed in petitioning Him about that thing, it shall be done for them of His Father which is in heaven. But further, it is not merely union in prayer for the same thing-for that might be with very jarring ideas of the thing to be desired-but it is to symphonious prayer, the prayer by kindred spirits, members of one family, servants of one Lord, constrained by the same love, fighting under one banner, cheered by assurances of the same victory; a living and loving union, whose voice in the divine ear is as the sound of many waters. Accordingly, what they ask "on earth" is done for them, says Jesus, "of My Father which is in heaven." Not for nothing does He say, "of My Father"-not "YOUR Father"; as is evident from what follows: "For where two or three are gathered together unto My name"-the "My" is emphatic, "there am I in the midst of them." As His name would prove a spell to draw together many clusters of His dear disciples, so if there should be but two or three, that will attract Himself down into the midst of them; and related as He is to both the parties, the petitioners and the Petitioned-to the one on earth by the tie of His assumed flesh, and to the other in heaven by the tie of His eternal Spirit-their symphonious prayers on earth would thrill upward through Him to heaven, be carried by Him into the holiest of all, and so reach the Throne. Thus will He be the living Conductor of the prayer upward, and the answer downward.

Parable of the Unmerciful Debtor (Mt 18:21-35).

Matthew Henry's Concise Commentary

18:15-20 If a professed Christian is wronged by another, he ought not to complain of it to others, as is often done merely upon report, but to go to the offender privately, state the matter kindly, and show him his conduct. This would generally have all the desired effect with a true Christian, and the parties would be reconciled. The principles of these rules may be practised every where, and under all circumstances, though they are too much neglected by all. But how few try the method which Christ has expressly enjoined to all his disciples! In all our proceedings we should seek direction in prayer; we cannot too highly prize the promises of God. Wherever and whenever we meet in the name of Christ, we should consider him as present in the midst of us.
