Revelation 3:5

He that overcometh. — The promise is repeated to all who overcome; all, not who have never fallen, or failed, but who conquer, shall be clothed in glistening white raiment. On this glistering appearance comp. Dante’s words, “robed in hue of living flame,” and the description so frequent in the Pilgrim’s Progress — “the shining ones.” Trench, who reminds us that this glistening white is found in the symbolism of heathen antiquity, says: “The glorified body, defecated of all its dregs and impurities, whatever remained of those having been precipitated in death, and now transformed and transfigured into the likeness of Christ’s body (Philippians 3:21), this, with its robe, atmosphere, and effluence of lights, is itself, I believe, the white raiment which Christ here promises to His redeemed.” Professor Lightfoot thinks (see his Epistle to Col. p. 22) that there may be a reference to the purple dyes for which Sardis, as well as Thyatira, was celebrated.

I will not blot out... — The negative is emphatic, “I will in no wise blot out.” This figure of speech — a book and the blotting out — was ancient. (See Deuteronomy 32:32; Psalms 69:21; Daniel 12:1; comp. also Luke 10:20; Philippians 4:3.) The name shall not be erased from the roll or register of the citizens of heaven. “A process of erasure is ever going on, besides the process of entering. When the soul has finally taken its choice for evil, when Christ is utterly denied on earth and trodden under foot, when the defilement of sin has become inveterate and indelible, then the pen is drawn through the guilty name, then the inverted style smears the wax over the unworthy characters; and when the owner of that name applies afterwards for admittance, the answer is, ‘I know thee not; depart hence, thou willing worker and lover of iniquity’” (Dr. Vaughan).

But I will confess his name. — Another echo of Christ’s words on earth (Matthew 10:32; Luke 12:8).
