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.
8. I have set—Greek, "given": it is My gracious gift to thee.
open door—for evangelization; a door of spiritual usefulness. The opening of a door by Him to the Philadelphian Church accords with the previous assignation to Him of "the key of David."
and—The three oldest manuscripts, A, B, C, and Origen read, "which no man can shut."
for—"because."
a little—This gives the idea that Christ says, He sets before Philadelphia an open door because she has some little strength; whereas the sense rather is, He does so because she has "but little strength": being consciously weak herself, she is the fitter object for God's power to rest on [so Aquinas], that so the Lord Christ may have all the glory.
and hast kept—and so, the littleness of thy strength becoming the source of Almighty power to thee, as leading thee to rest wholly on My great power, thou hast kept My word. Grotius makes "little strength" to mean that she had a Church small in numbers and external resources: "a little flock poor in worldly goods, and of small account in the eyes of men" [Trench]. So Alford. I prefer the view given above. The Greek verbs are in the aorist tense: "Thou didst keep … didst not deny My name": alluding to some particular occasion when her faithfulness was put to the test.
