And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof? A strong angel - One of the chief of the angelic host.
Proclaiming - As the herald of God.
To open the book, and to loose the seals - To loose the seals that he may open the book. Who can tell what this book contains? Who can open its mysteries? The book may mean the purposes and designs of God relative to his government of the world and the Church; but we, whose habitation is in the dust, know nothing of such things. We are, however, determined to guess.
