1. Who they are that shall be added to the church—people, and the inhabitants of many cities (v. 20); not only a few ignorant country people that may be easily imposed upon, or some idle people that have nothing else to do, but intelligent inquisitive citizens, men of business and acquaintance with the world, shall embrace the gospel of Christ; yea, many people and strong nations (v. 22), some of all languages, v. 23. By this it appears that they are brought into the church, not by human persuasion, for they are of different languages, not by external force, for they are strong nations, able to have kept their ground if they had been so attacked, but purely by the effectual working of divine truth and grace. Note, God has his remnant in all parts; and in the general assembly of the church of the first-born some will be found out of all nations and kindreds, Rev. vii. 9.
