ISB ~ Revelation 3 v12

pillar in the temple:Believers form a living temple indwelt with the Spirit and glory of God (Eph 2:19-22). To be a pillar is to stand in an honored position (Gal 2:9). The stability of a pillar contrasts with the instability of the city, which was leveled by an earthquake in A.D. 17.

my God:Jesus is not denying his own divinity but speaks from the standpoint of his humanity, which he shares in common with us (as in Jn 20:17).

the name:The righteous will bear the names of the Father and the Son (14:1) and be identified as citizens of the heavenly Jerusalem (21:2-4). This may recall how Philadelphia was renamed (Neo-Caesarea) after the earthquake.
