3:7 {6} And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the {e} key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;
(6) The sixth passage is to the pastors of Philadelphia. The introduction is taken from Re 1:18.
(e) All power of rule in commanding and forbidding, in delivering and punishing. The house of David is the Church, and the continual promise of David's kingdom belongs to Christ.
3:7 THE CHURCH AT PHILADELPHIA
The church in Philadelphia. This city was in the interior, southeast of Sardis, and had never attained the eminence of most of the other seats of the Seven Churches. That the church itself was poor and wanting in worldly endowments seems to be indicated by Re 3:8. Yet this church and that of Smyrna alone escape censure. Philadelphia is yet a city of 18,000 inhabitants, though bearing a Turkish name, has five churches and a Christian population of about 3,000.
He that hath the key of David. See PNT Re 1:18. The key of the kingdom of God as the Son of David. Hence he only opens and shuts, or determines who shall enter in, or be shut out.
3:7 The holy one, the true one - Two great and glorious names He that hath the key of David - A master of a family, or a prince, has one or more keys, wherewith he can open and shut all the doors of his house or palace. So had David a key, a token of right and sovereignty, which was afterward adjudged to Eliakim, Isaiah 22:22. Much more has Christ, the Son of David, the key of the spiritual city of David, the New Jerusalem; the supreme right, power, and authority, as in his own house. He openeth this to all that overcome, and none shutteth: he shutteth it against all the fearful, and none openeth. Likewise when he openeth a door on earth for his works or his servants, none can shut; and when he shutteth against whatever would hurt or defile, none can open.
3:7-13 The same Lord Jesus has the key of government and authority in and over the church. He opens a door of opportunity to his churches; he opens a door of utterance to his ministers; he opens a door of entrance, opens the heart. He shuts the door of heaven against the foolish, who sleep away their day of grace; and against the workers of iniquity, how vain and confident soever they may be. The church in Philadelphia is commended; yet with a gentle reproof. Although Christ accepts a little strength, yet believers must not rest satisfied in a little, but strive to grow in grace, to be strong in faith, giving glory to God. Christ can discover this his favour to his people, so that their enemies shall be forced to acknowledge it. This, by the grace of Christ, will soften their enemies, and make them desire to be admitted into communion with his people. Christ promises preserving grace in the most trying times, as the reward of past faithfulness; To him that hath shall be given. Those who keep the gospel in a time of peace, shall be kept by Christ in an hour of temptation; and the same Divine grace that has made them fruitful in times of peace, will make them faithful in times of persecution. Christ promises a glorious reward to the victorious believer. He shall be a monumental pillar in the temple of God; a monument of the free and powerful grace of God; a monument that shall never be defaced or removed. On this pillar shall be written the new name of Christ; by this will appear, under whom the believer fought the good fight, and came off victorious.
