John Gill's Exposition of the Whole Bible
Psalms 45:15
With, gladness and rejoicing shall they be brought,.... With joy unspeakable, and full of glory in themselves, because of what they shall be delivered from; from all outward troubles and afflictions; from all inward distresses, darkness, doubts, and fears; from sin, Satan, and all spiritual enemies; and because of what they shall enjoy, communion with God, angels and saints, the vision of God in Christ, conformity to him, perfect knowledge, complete holiness and happiness, and a glory both upon their souls and bodies: they shall also be brought with the joy of Christ's faithful minister, who will rejoice in that day that they have not run nor laboured in vain; and with the joy of all the holy angels; and with the joy of Christ the King himself, who always rejoiced in them and over them; yea, with the rejoicing of Father, Son, and Spirit: the Father will rejoice to see those brought in whom he has loved with an everlasting love, has chosen in Christ, given to him, and whom he sent his Son to redeem: the Son of God will rejoice to see those presented to him whom he has loved and betrothed to himself; who are the purchase of his blood, and the travail of his soul; who are his jewels, treasure and portion: and the Holy Spirit will rejoice to see those brought to glory whom he has been the convincer, comforter, and sealer of; whom he has been at work upon, and has wrought them up for this selfsame thing:
they shall enter into the King's palace; into heaven, the palace of the King Messiah, the King of kings and King of saints; where are mansions preparing for them, suitable to their high birth and character, as the daughters of a king; and where they shall enter, not merely to see it and go out again, but to dwell in it with their Lord, Head, and Husband, for evermore; and that as in their own palace, upon the foot of their relation to Christ, interest in him, right and meetness by him.
