Vs. 7-13.—­This church, like the one in Smyrna, is “without rebuke,” in the midst of similar trials.—­Christ’s message is prefaced, as usual, by some description of himself, implying his supreme deity and authority.  “He that is holy, he that is true,” is more than a creature.  As “there is none good but one, that is God;” so, “there is none holy as the Lord,” (Jehovah,) (1 Sam. ii. 2.) Here is another, among many plain proofs, of our Saviour’s proper divinity.  His divine authority is held forth in his “having the key of David,” etc.  A key is the symbol of authority, (Matt. xvi. 19,) and the reference is to that prophecy, (Isa. xxii. 20-24,) in which the mediatorial dominion of Christ is set forth, by calling Eliakim to the place of authority in the room of Shebna.  “The key of the house of David will I lay upon his shoulder.”  It is in virtue of this extensive grant of power from the Father, that the Lord Christ has a right, as Mediator, to send his ambassadors into all nations, to call sinners (rebels) back to their rightful allegiance; and also to execute deserved punishment upon all who do harm to his servants. (Ps. cv, 15.) In the exercise of his rightful authority, he has set before this church an “open door” of liberty, of opportunity, of activity; that she may put forth her “little strength” in keeping Christ’s word and confessing his name amidst opposition, reproach and violence; for it is obvious, that when impostors fail to reach their objects by deceit, they will resort to forcible measures.  Because this church was unable to purge herself by corrective discipline,—­having but “a little strength,” therefore Christ declares his purpose to strip these lying Jews of their cloak of hypocrisy, and exhibit them in their true character a “synagogue (church) of Satan.” (James ii. 2.) Seeing that in apostolic times there were apostles, ministers, churches of the devil, is it to be supposed that we violate the law of charity, if in our own degenerate age, when heresies abound, when ecclesiastical order is trampled upon, we venture to apply the language of the Holy Spirit to unholy and profane amalgamations?  No, it is part of the special business of Christ’s witnesses to unmask specious hypocrites and warn of danger from false teachers, (2 Cor. xi. 13-15; Gal. i. 6, 7,) that “their folly may be made manifest to all men.” (2 Tim. iii. 8, 9; 2 Peter ii. 1, 3.)—­The cruel enemy, who in the day of prosperity boasts of his success, in the day of adversity becomes the most arrant coward and cringing suppliant,—­whether it be Saul or Shimei. (1 Sam. xv. 30; 2 Sam. xix. 18.) Haughty persecutors have been changed to humble suitors for an interest in the prayers of their victims,—­“to worship before their feet.”  “The word of Christ’s patience” may signify any truth or doctrine of the Bible which is of supernatural revelation.  The same idea is suggested by the phrase, “the present truth,”—­any divine truth which may come to be opposed or denied,
