Relevant Words of God:
In every age in which God personally does His own work, He uses a name that befits the age in order to encapsulate the work that He intends to do. He uses this particular name, one that possesses temporal significance, to represent His disposition in that age. This is God using the language of mankind to express His own disposition.
from “The Vision of God’s Work (3)” in The Word Appears in the Flesh
