3:8 {7} I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
(7) The note of praise is in this verse of promises, and Re 3:9 to bring home again them that wander, in Re 3:10 to preserve the godly and in Re 3:11 to exhort.
3:8 I have set before thee an open door. Compare Ac 14:27 1Co 16:9 2Co 2:12 Col 4:3. The open door means great opportunities; generally for preaching the gospel. It probably means here, a way opened to convert the Gentiles.
For thou hast a little strength, and hast kept my word. Through their strength was not great, they had remained faithful in much opposition.
And hast not denied my name. The Pagan authorities often tested Christians by commanding them to blaspheme the name of Christ under penalty of death.
3:8 I have given before thee an opened door - To enter into the joy of thy Lord; and, meantime, to go on unhindered in every good work. Thou hast a little strength - But little outward human strength; a little, poor, mean, despicable company. Yet thou hast kept my word - Both in judgment and practice.
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.
