Hitherto the apostle had seen only the great God, the governor of all things, now,

I.He is favoured with a sight of the model and methods of his government, as they are all written down in a book which he holds in his hand; and this we are now to consider as shut up and sealed in the hand of God. Observe, 1. The designs and methods of divine Providence towards the church and the world are stated and fixed; they are resolved upon and agreed to, as that which is written in a book. The great design is laid, every part adjusted, all determined, and every thing passed into decree and made a matter of record. The original and first draught of this book is the book of God's decrees, laid up in his own cabinet, in his eternal mind: but there is a transcript of so much as was necessary to be known in the book of the scriptures in general, in the prophetical part of the scripture especially, and in this prophecy in particular. 2. God holds this book in his right hand, to declare the authority of the book, and his readiness and resolution to execute all the contents thereof, all the counsels and purposes therein recorded. 3. This book in the hand of God is shut up and sealed; it is known to none but himself, till he allows it to be opened. Known unto God, and to him alone, are all his works, from the beginning of the world; but it is his glory to conceal the matter as he pleases. The times and seasons, and their great events, he hath kept in his own hand and power. 4. It is sealed with seven seals. This tells us with what inscrutable secrecy the counsels of God are laid, how impenetrable by the eye and intellect of the creature; and also points us to seven several parts of this book of God's counsels. Each part seems to have its particular seal, and, when opened, discovers its proper events; these seven parts are not unsealed and opened at once, but successively, one scene of Providence introducing another, and explaining it, till the whole mystery of God's counsel and conduct be finished in the world.

II.He heard a proclamation made concerning this sealed book. 1. The crier was a strong angel; not that there are any weak ones among the angels in heaven, though there are many among the angels of the churches. This angel seems to come out, not only as a crier, but as a champion, with a challenge to any or all the creatures to try the strength of their wisdom in opening the counsels of God; and, as a champion, he cried with a loud voice, that every creature might hear. 2. The cry or challenge proclaimed was, "Who is worthy to open the book, and to loose the seals thereof? Rev 5:2. If there by any creature who thinks himself sufficient either to explain or execute the counsels of God, let him stand forth, and make the attempt." 3. None in heaven or earth could accept the challenge and undertake the task: none in heaven, none of the glorious holy angels, though before the throne of God, and the ministers of his providence; they with all their wisdom cannot dive into the decrees of God: none on earth, no man, the wisest or the best of men, none of the magicians and soothsayers, none of the prophets of God, any further than he reveals his mind to them: none under the earth, none of the fallen angels, none of the spirits of men departed, though they should return to our world, can open this book. Satan himself, with all his subtlety, cannot do it; the creatures cannot open it, nor look on it; they cannot read it. God only can do it.

III.He felt a great concern in himself about this matter: the apostle wept much; it was a great disappointment to him. By what he had seen in him who sat upon the throne, he was very desirous to see and know more of his mind and will: this desire, when not presently gratified, filled him with sorrow, and fetched many tears from his eyes. Here observe, 1. Those who have seen most of God in this world are most desirous to see more; and those who have seen his glory desire to know his will. 2. Good men may be too eager and to hasty to look into the mysteries of divine conduct. 3. Such desires, not presently answered, turn to grief and sorrow. Hope deferred makes the heart sick.

IV.The apostle was comforted and encouraged to hope this sealed book would yet be opened. Here observe, 1. Who it was that gave John the hint: One of the elders. God had revealed it to his church. If angels do not refuse to learn from the church, ministers should not disdain to do it. God can make his people to instruct and inform their teachers when he pleases. 2. Who it was that would do the thing - the Lord Jesus Christ, called the lion of the tribe of Judah, according to his human nature, alluding to Jacob's prophecy (Gen 49:10), and the root of David according to his divine nature, though a branch of David according to the flesh. He who is a middle person, God and man, and bears the office of Mediator between God and man, is fit and worthy to open and execute all the counsels of God towards men. And this he does in his mediatorial state and capacity, as the root of David and the offspring of Judah, and as the King and head of the Israel of God; and he will do it, to the consolation and joy of all his people.

A book written within and on the back side - That is, the book was full of solemn contents within, but it was sealed; and on the back side was a superscription indicating its contents. It was a labelled book, or one written on each side of the skin, which was not usual.

Sealed with seven seals - As seven is a number of perfection, it may mean that the book was so sealed that the seals could neither be counterfeited nor broken; i.e., the matter of the book was so obscure and enigmatical and the work it enjoined and the facts it predicted so difficult and stupendous, that they could neither be known nor performed by human wisdom or power.

And I saw on the right hand of him that sat on the throne,.... Of this throne, and who it was that sat upon it; see Gill on Rev 4:2; and who had "in" his right hand, or "at", or "upon" his right hand, as the Syriac and Arabic versions render it, lying by, or near his right hand; though according to Rev 5:7, the book appears to have been in his right hand, as our version, and others render it:

a book written within, and on the backside, sealed with seven seals: this book was very much like Ezekiel's roll, Eze 2:9; which was written , "within" and "without", before and behind, and indeed it was in the form of a roll: the manner of writings in those times was on sheets of parchment, which, when finished, were rolled up in the form of a cylinder; hence a book is called a "volume". This book seems to have consisted of seven rolls, to which was annexed seven seals; and there being not room enough within, contrary to the common way of writing, some things were written upon the backside of the outermost roll; and such writings were by the ancients called "Opistographi": and the word is used by them sometimes for very prolix writings (b). By this book some understand the Scriptures of the Old Testament, which were written in rolls; see Heb 10:5; and which came out of the right hand of God, and were given forth by him; and being written within, and on the backside, may denote the fulness of them, they containing a variety of matter, useful and profitable, for different purposes; or else the literal and mystical, or spiritual meaning of some parts of them: or, as others think, the more clear explanation of the books of the Old Testament, by those of the New Testament; and its being sealed may signify the authenticity of those writings, having the seal of God's truth, and the impress of his wisdom, power, and goodness on them; and also the hidden sense and meaning of them, they being, especially in the prophetic and spiritual part of them, a sealed book to natural men, and of which Christ is the truest and best interpreter; but then this book was opened, and looked into, and read, and, in some measure, understood, even by the Old Testament saints, and had been before this time expounded by Christ, concerning himself; yea, he had opened the understandings of his disciples to understand those Scriptures, and had counted them, and others, worthy to open and explain this book to others, and had sent them into all the world for this purpose; and for the same reasons it cannot be understood of the Gospel published to Jews and Gentiles, the one within, and the other without; rather therefore the book of God's decrees is here meant, which respects all creatures, and all occurrences and events in the whole world, from the beginning to the end of time; and so Ezekiel's roll, according to the Targum on Eze 2:10; which was written before and behind, signified that which was , "from the beginning", and which , "shall be in the end", or hereafter. This book God holds "in his right hand", as the rule and measure of all he does, and of the government of the world, and which he constantly fulfils and executes; and its being written "within and without" may denote the perfection and comprehensiveness of it, it reaching to all creatures and things, even the most minute; and its being "sealed" shows the certainty of its fulfilment, and the secrecy and hiddenness of it, until accomplished; though it seems best of all to understand it of that part of God's decrees relating to the church and world, particularly the Roman empire, which from henceforward, to the end of time, was to be fulfilled; and so is no other than the book of the Revelation itself, exhibited in the following scenes and visions; and this may be truly said to be in the right hand of God, and from thence taken by the Lamb, it being the revelation of Jesus Christ, which God gave unto him, Rev 1:1; and may be said to be written, both "within and on the backside", to show that it contains a large account of things, a long train of events to be accomplished; as also to signify, that it regards the church, and the members of it, who are those that are within, in the several ages of time, and the world, or those that are without; for this book prophecy regards both the state of the Roman empire, and of the Christian church; and its being "sealed" shows the authenticity, certainty, and also the obscurity of what was contained therein; and with "seven" seals, with respect to the seven periods of time, in which the prophecies in it are to be fulfilled.
