Revelation 5:2

Observe, 1. Here is. proclamation made by an extraordinary angel, like an herald or officer, inquiring who was worthy, either in regard of authority, or in respect of ability, to open this book, and unloose the seals, that is, to disclose the secret counsels of God, and to make them known unto the sons of men, implying, that every angel in heaven is not worthy or meet to be the expositor of God's mind and mysteries unto man.

Observe, 2. The great silence which there was in heaven upon this proclamation, amounting to an absolute and peremptory denial, that not any one, either in heaven or earth, or under the earth; not any angel in heaven, nor any saint living upon earth; not any dead saint under the earth, nor any devil or infernal spirit; was either worthy to open the book, or able to foresee or foretell the least event concerning the church, farther than revealed to them.

Learn hence, That neither angels nor devils do understand the mysterious counsels of God, or can reveal future things to man, any farther than as God is pleased to reveal the same unto them.

Observe, 3. St. John's great and bitter lamentation, because no person was found worthy to open the book, and reveal unto the church the secret counsels of God concerning her, I wept much; fearing, no doubt, lest the church of God should be deprived of the benefit and comfort of this revelation. Such as are the true members of the church are greatly afflicted with all the providential dispensations of God which do befall her; but nothing goes so near them, as to have the mind and will of God hidden and concealed from her.

Observe, 4.. seasonable consolation given to St. John: one of the elders that were about the throne said to him, Weep not, for care is taken for the opening and revealing of the book. Christ, who is called the Lion of the tribe of Judah, the Son of David, as man, and the root of David, as God, is found worthy, in regard of the divinity of his person, and the prevalency of his merits, to open unto the church all the mysteries of God, which are meet and convenient for her to understand and know.

Quest. Why is Christ called the Lion of the tribe of Judah?

Ans. In allusion to Jacob's blessing, Genesis 49 where Judah is called. lion's whelp, denoting the dignity and superiority of that tribe above the rest.

Now Christ descended of this tribe, and is called. lion, in regard of his kingly power and strength, in regard of his stoutness and courage, in regard of his mildness and clemency, and true nobleness of spirit, to them that submit and yield unto him, and in respect of his vigilancy and watchfulness over his church; all which are the known properties of the lion; and as that creature is the king of beasts, so is Christ King of kings, and Lord of lords, the only potentate; dominion and fear are with him.

Quest. But how could Christ be called David's root, when we know that David did not spring from him, but he from David, according to the flesh?

Ans. In. natural sense, David was the root of David. David, as man, was the root of Christ: Christ, as Mediator and Godman, was the root of David. Thus he was both David's lord, and David's son, Psalms 110:1.
