7 And to the angel of the church in Philadelphia say: These things says he who is holy, he who is true, he who has the key of David, opening the door so that it may be shut by no one, and shutting it so that it may be open to no one. 8 I have knowledge of your works (see, I have put before you an open door which may be shut by no one), and that you have a little strength, and have kept my word, and have been true to my name. 9 See, I will make those of the Synagogue of Satan who say they are Jews, and are not, but say what is false; I will make them come and give worship before your feet, and see my love for you. 10 Because you have kept my word in quiet strength, I will keep you from the hour of testing which is coming on all the world, to put to the test those who are on earth. 11 I come quickly: keep that which you have, so that no one may take your crown. 12 Him who overcomes I will make a pillar in the house of my God, and he will go out no more: and I will put on him the name of my God, and the name of the town of my God, the new Jerusalem, which comes down out of heaven from my God, and my new name.

Commentary on Revelation 3:7-13
(Read Revelation 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.
