What does Revelation 3:12 mean?

Anyone who wins this fight, I’ll make them like a pillar in God’s temple—they’ll never have to leave. I’ll write God’s name on them, and the name of God’s city, the new Jerusalem coming down from heaven, and my own new name. Revelation 3:12 - Modern Text Bible

(The faithful will have a permanent, honored place with God, marked as belonging to him forever.)
