Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Rev 5:1-7) A book sealed with seven seals, which could be opened by none but Christ, who took the book to open it.
(Rev 5:8-14) Upon which all honour is ascribed to him, as worthy to open it.
The apostle saw in the hand of Him that sat upon the throne, a roll of parchments in the form usual in those times, and sealed with seven seals. This represented the secret purposes of God about to be revealed. The designs and methods of Divine Providence, toward the church and the world, are stated, fixed, and made a matter of record. The counsels of God are altogether hidden from the eye and understanding of the creature. The several parts are not unsealed and opened at once, but after each other, till the whole mystery of God's counsel and conduct is finished in the world. The creatures cannot open it, nor read it; the Lord only can do so. Those who see most of God, are most desirous to see more; and those who have seen his glory, desire to know his will. But even good men may be too eager and hasty to look into the mysteries of the Divine conduct. Such desires, if not soon answered, turn to grief and sorrow. If John wept much because he could not look into the book of God's decrees, what reason have many to shed floods of tears for their ignorance of the gospel of Christ! of that on which everlasting salvation depends! We need not weep that we cannot foresee future events respecting ourselves in this world; the eager expectation of future prospects, or the foresight of future calamities, would alike unfit us for present duties and conflicts, or render our prosperous days distressing. Yet we may desire to learn, from the promises and prophecies of Scripture, what will be the final event to believers and to the church; and the Incarnate Son has prevailed, that we should learn all that we need to know. Christ stands as Mediator between God and both ministers and people. He is called a Lion, but he appears as a Lamb slain. He appears with the marks of his sufferings, to show that he pleads for us in heaven, in virtue of his satisfaction. He appears as a Lamb, having seven horns and seven eyes; perfect power to execute all the will of God, and perfect wisdom to understand it, and to do it in the most effectual manner. The Father put the book of his eternal counsels into the hand of Christ, and Christ readily and gladly took it into his hand; for he delights to make known the will of his Father; and the Holy Spirit is given by him to reveal the truth and will of God.
It is matter of joy to all the world, to see that God deals with men in grace and mercy through the Redeemer. He governs the world, not merely as a Creator, but as our Saviour. The harps were instruments of praise; the vials were full of odours, or incense, which signify the prayers of the saints: prayer and praise should always go together. Christ has redeemed his people from the bondage of sin, guilt, and Satan. He has not only purchased liberty for them, but the highest honour and preferment; he made them kings and priests; kings, to rule over their own spirits, and to overcome the world, and the evil one; and he makes them priests; giving them access to himself, and liberty to offer up spiritual sacrifices. What words can more fully declare that Christ is, and ought to be worshipped, equally with the Father, by all creatures, to all eternity! Happy those who shall adore and praise in heaven, and who shall for ever bless the Lamb, who delivered and set them apart for himself by his blood. How worthy art thou, O God, Father, Son, and Holy Ghost, of our highest praises! All creatures should proclaim thy greatness, and adore thy majesty.
