Matthew 18:20

For where two - are gathered together in thy name - There are many sayings among the Jews almost exactly similar to this, such as, Wherever even two persons are sitting in discourse concerning the law, the Divine presence is among them. See much more in Schoettgen. And the following, among the ancient Hindoos, is like unto it: "When Brahma, the Lord of creation, had formed mankind, and at the same time appointed his worship, he spoke and said, 'With this worship pray for increase, and let it be that on which ye shall depend for the accomplishment of all your wishes. With this remember God, that God may remember you. Remember one another, and ye shall obtain supreme happiness. God, being remembered in worship, will grant you the enjoyment of your wishes: he who enjoyeth what hath been given unto him by God, and offereth not a portion unto him, is even as a thief. Know that good works come from Brahma, whose nature is incorruptible; wherefore, the omnipresent Brahma is Present In The Worship." See the Bagvat Geeta, p. 45, 46.

In my name - Seems to refer particularly to a public profession of Christ and his Gospel.

There am I in the midst - None but God could say these words, to say them with truth, because God alone is every where present, and these words refer to his omnipresence. Wherever - suppose millions of assemblies were collected in the same moment, in different places of the creation, (which is a very possible case), this promise states that Jesus is in each of them. Can any, therefore, say these words, except that God who fills both heaven and earth? But Jesus says these words: ergo - Jesus is God. Let it be observed, that Jesus is not among them to spy out their sins; or to mark down the imperfections of their worship; but to enlighten, strengthen, comfort, and save them.

For where two or three ... - This is a general assertion made to support the particular promise made Matthew 18:19 to his apostles. He affirms that wherever two or three are assembled together in his name, he is in the midst of them.

In my name - That is,

1. By my authority, acting for me in my church. See John 10:25; John 16:23.

2. It may mean for my service; in the place of prayer and praise, assembled in obedience to my commend, and with a desire to promote my glory.

There am I in the midst of them - Nothing could more clearly prove that Jesus must be omnipresent, and, of course, be God. Every day, perhaps every hour, two or three, or many more, may be assembled in every city or village in the United States, in England, in Greenland, in Africa, in Ceylon, in the Sandwich Islands, in Russia, and in Judea - in almost every part of the world - and in the midst of them all is Jesus the Saviour. Millions thus at the same time, in every quarter of the globe, worship in his name, and experience the truth of the promise that he is present with them. It is impossible that he should be in all these places and not be God.

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.
