Will I make a pillar. — A pillar, and an unshaken one. There may be reference to the frequent earthquakes which had shaken down buildings in their city. Those who overcome will prove real supports to the great Christian temple. (Comp. Galatians 2:9.)
Write upon him. — Or, grave upon it. On the sides of the four marble pillars which survive as ruins of Philadelphia inscriptions are to be found. The writing would be the name of God, the name of the heavenly Jerusalem and (omit the repetition, “I will write upon him”) the new, unknown name of Christ Himself. The allusion is to the golden frontlet inscribed with the name of Jehovah. (Comp. Revelation 22:4.) He will reflect the likeness of God; and not only so, he will bear the tokens — now seen in all clearness — of his heavenly citizenship (Philippians 3:20; Hebrews 12:22-23). And a further promise implies that in the day of the last triumph, as there will be new revealings of Christ’s power, there will be unfolded to the faithful and victorious new and higher possibilities of purity. Thus does Scripture refuse to recognise any finality which is not a beginning as well as an end — a landing-stage in the great law of continuity. (See Revelation 2:17; Revelation 19:12.)
