If E = mc2 then we can divide and conclude that...
Mass (m) = Energy (E/c2)
And there are three varieties...
Natural E/c2 - All mass is basically cooled plasma
Mental E/c2 - Mentally, A mathematical formula, but this has chemical and spiritual properties as well.
Spiritual E/c2 - E (motivation, warmth, love) / c2 (faith, hope, charity, joy)
God the Father is light and energy. Light and energy cannot be created or destroyed, it merely changes form throughout the eternal ages. God the Father, though, stays the same, but his energy and light has changed form to create many things.
But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. -
2 Peter 3:10
God is soon going to disassociate the mass of the universe into the light and energy from whence it was forged and do something else with it. Judging by the size of the universe that is going to be a lot of E/c2 to play with!
