Psalm 145:11

They shall speak of the glory of thy kingdom
That is, the saints who are his special workmanship, in the celebration of his praise; and, while they are blessing him, will take particular notice, and make particular mention of his kingdom, and the glory of it; not only his kingdom of nature and providence, which ruleth over all, angels and men, good and bad; which deserves the notice of the saints, and is matter of great joy unto them, that their King reigns in the world, but also, and rather, his kingdom of grace, in which he rules by his Spirit and grace in the hearts of his people; which is not worldly, but spiritual; is not with outward observation, but lies within the heart, and makes the Lord's people all glorious within; consisting of peace, righteousness, and joy in the Holy Ghost, and is what can never be removed. The church is Christ's kingdom, in which he reigns; and all the subjects of it are kings and priests unto God: here proper laws are made and observed, and officers appointed to explain them, and see them put in execution; glorious ordinances are administered, in which Christ the King is seen in his beauty; and the glorious Gospel, which is his sceptre, is held forth, and by which he rules in the midst of his enemies. More especially this may regard the glorious kingdom of Christ in the latter day; both in his spiritual reign, in which there will be a great display of glory; as a large effusion of the Spirit; much spiritual light and knowledge; great holiness of heart and life; an abundance of peace, temporal and spiritual; great purity of Gospel doctrine, worship, and ordinances: and also in his personal reign; when he will appear glorious, and reign before his ancients gloriously, and his saints will appear with him in glory; the New Jerusalem will have the glory of God upon her; a glory there will be then both upon the bodies and souls of the saints Christ will have with him in that state: and talk of thy power;
not only as exerted in creation and providence; but of his power in working out the salvation of men; and in conquering and subduing all the spiritual enemies of his people, sin, Satan, the world, and death; in raising himself from the dead, as he will all his saints by the same power at the last day; in going forth into the Gentile world in the ministry of the word, conquering and to conquer, making it powerful and effectual to the conversion of thousands: and also of his power in heaven and in earth, given him as Mediator; and which he has exercised and does exercise on the behalf of his church, and for its protection and welfare: and especially of the more open display of it in the latter day, when he shall take to himself his great power and reign; then will his saints talk of it with great pleasure and thankfulness; see ( Revelation 11:15-17 ) .
