7 'And to the messenger of the assembly in Philadelphia write: These things saith he who is holy, he who is true, he who is having the key of David, he who is opening and no one doth shut, and he shutteth and no one doth open! 8 I have known thy works; lo, I have set before thee a door—opened, and no one is able to shut it, because thou hast a little power, and didst keep my word, and didst not deny my name; 9 lo, I make of the synagogue of the Adversary those saying themselves to be Jews, and are not, but do lie; lo, I will make them that they may come and bow before thy feet, and may know that I loved thee. 10 'Because thou didst keep the word of my endurance, I also will keep thee from the hour of the trial that is about to come upon all the world, to try those dwelling upon the earth. 11 Lo, I come quickly, be holding fast that which thou hast, that no one may receive thy crown. 12 He who is overcoming—I will make him a pillar in the sanctuary of my God, and without he may not go any more, and I will write upon him the name of my God, and the name of the city of my God, the new Jerusalem, that doth come down out of the heaven from my God—also 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.
