Isaiah 25:9

And it shall be said in that day
When the feast will be made for all the Lord's people; when the veil and covering shall be removed; when death will be swallowed up in victory; when all tears shall be wiped away from the saints; when their rebuke shall be taken away from them; all which will be at the glorious appearing of Christ. Lo, this [is] our God;
and not the idols of the Gentiles, or the works of their hands; but Christ, who is God over all, blessed for ever; Immanuel, God with us: the phrase is expressive of his true and proper deity, of faith of interest in him, and of the joy of it: we have waited for him, and he will save us:
as the Old Testament saints waited for his first coming, and for his salvation, believing that he would be the author of it: so New Testament saints are waiting for his second coming; and to them that look for him, and expect his glorious appearing, who have their loins girt, and their lights burning, and wait for their Lord's coming, will he appear a second time without sin unto salvation; to put them into the possession of salvation he has obtained for them, for which they are heirs, and is nearer than when they believed: this [is] the Lord, we have waited for him;
looking, longing, and hasting to the day of his coming; this they will say, when they shall see him coming in the clouds of heaven; whither the living saints being changed, will be caught up to meet him, and upon meeting him shall thus greet him, and one another: we will be glad, and rejoice in his salvation;
so suitable to them, so full, complete, and perfect, and so much for the glory of God; which was wrought out by him before, and now possessed by them; and is what is called the "joy" of their "Lord", they now "enter" into, ( Matthew 25:21 ) .
