5. That the church and ministry, being thus settled, shall continue and be kept up in a succession from one generation to another, v. 22. The change that will be made by the setting up of the kingdom of the Messiah is here described to be, (1.) A very great and universal change; it shall be a new world, the new heavens and the new earth promised before, ch. lxv. 17. Old things have passed away, behold all things have become new (2 Cor. v. 17), the old covenant of peculiarity is set aside, and a new covenant, a covenant of grace, established, Heb. viii. 13. We are now to serve in newness of the spirit, and not in the oldness of the letter, Rom. vii. 6. New commandments are given relating both to heaven and earth, and new promises relating to both, and both together make a New Testament; so that they are new heavens and a new earth that God will create, and these a preparative for the new heavens and new earth designed at the end of time, 2 Pet. iii. 13. (2.) A change of God's own making; he will create the new heavens and the new earth. The change was made by him that had authority to make new ordinances, as well as power to make new worlds. (3.) It will be an abiding lasting change, a change never to be changed, a new world that will be always new, and never wax old, as that does which is ready to vanish away: It shall remain before me unalterable; for the gospel dispensation is to continue to the end of time and not to be succeeded by any other. The kingdom of Christ is a kingdom that cannot be moved; the laws and privileges of it are things that cannot be shaken, but shall for ever remain, Heb. xii. 27, 28. It shall therefore remain, because it is before God; it is under his eye, and care, and special protection. (4.) It will be maintained in a seed that shall serve Christ: Your seed, and in them your name, shall remain—a seed of ministers, a seed of Christians; as one generation of both passes away, another generation shall come; and thus the name of Christ, with that of Christians, shall continue on earth while the earth remains, and his throne as the days of heaven. The gates of hell, though they fight against the church, shall not prevail, nor wear out the saints of the Most High.
