This concludes the magnificent introduction to the principal visions in this book. It is beautifully appropriate to the solemn disclosures which are to be made in the following portions of the book, and, as in the case of Isaiah and Ezekiel, was eminently adapted to impress the mind of the holy seer with awe. Heaven is opened to his view; the throne of God is seen; there is a vision of Him who sits upon that throne; thunders and voices are heard around the throne; the lightnings play; and a rainbow, symbol of peace, encircles all; the representatives of the redeemed church, occupying subordinate thrones, and in robes of victory, and with crowns on their heads, are there; a vast smooth expanse like the sea is spread out before the throne; and the emblems of the wisdom, the power, the vigilance, the energy, the strength of the divine administration are there, represented as in the act of bringing honour to God, and proclaiming his praise. The mind of John was doubtless prepared by these august visions for the disclosures which follow; and the mind of the reader should in like manner be deeply and solemnly impressed when he contemplates them, as if _he_ looked into heaven, and saw the impressive grandeur of the worship there. Let us fancy ourselves, therefore, with the holy seer looking into heaven, and listen with reverence to what the great God discloses respecting the various changes that are to occur until every foe of the church shall be subdued, and the earth shall acknowledge his sway, and the whole scene shall close in the triumphs and joys of heaven.
