But be you glad, and rejoice for ever in that which I create,.... This may refer either to persons converted, both at the beginning of the Gospel, and in the latter day, whether Jews or Gentiles; who are the Lord's creation, or new creatures, being made new men; having new hearts and spirits given them, or created within them; new principles of life, light, grace, and holiness, wrought in them, which are the produce of almighty and creating power; and all such instances are matter of joy, as to the angels in heaven, so to the saints on earth, and especially to the ministers of the Gospel; because of the grace bestowed on men, the glory brought to God, and their own ministry blessed and succeeded, and so their hands and hearts strengthened: or else this refers to the state of things under the Gospel dispensation, in every age of it, and especially in some periods of it, particularly the first and last; and the whole indeed is a new world or state of God's creating, and is matter of joy to all the people of God.
The Targum renders it,"rejoice in the world of worlds, which I create:''agreeably to which is the version of Bishop Chandler ,"rejoice for the age to come, that I create;''the world to come, Heb 2:5, which Christ is said to be the father of, in the Septuagint version of Isa 9:6, the Gospel dispensation, the Messiah's future world, as opposed to the legal dispensation.
For, behold, I create Jerusalem a rejoicing, and her people a joy; that is, do that for them, through the mighty power of his grace, as will justly occasion joy to them, and to all others well affected to them; the conversion of the Jews will be matter of joy to the Gentiles; and that, and the bringing in of the fulness of the Gentiles, as well as the destruction of antichrist, which will occasion a new face of things in the world, will be matter of joy to the whole church; see Re 18:20.
