52 Behold, nearest unto the sun is the planet Mercury, as it shall be known among you in the latter days. And this planet shall be transformed into a state that shall be the eternal world of those who belongeth to the highest degree of glory of the Celestial kingdom.
53 And it shall be called, Shinehahsan, like unto the kingdom of glory in which the Father dwelleth. And upon this planet shall an atmosphere be created by the power of God that shall shield it from the heat of Kolob, which is the name by which the sun in its final glory shall be known in the eternal kingdoms of the Father.
