Why is "the name of my God" inscribed on this pillar?
Revelation 3:12 (ESV)
12The one who conquers, I will make him a pillar in the temple of my God. Never shall he go out of it, and I will write on him the name of my God,and the name of the city of my God, the new Jerusalem, which comes down from my God out of heaven, and my own new name.
The name is a mark of ownership. God’s name was also placed upon his Old Testament people (Numbers 6:27; Isaiah 43:7).
12 The one who conquers, I will make him a pillar in the temple of my God. Never shall he go out of it, and I will write on him the name of my God, and the name of the city of my God, the new Jerusalem, which comes down from my God out of heaven, and my own new name.
