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)
How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! - Isaiah 14:12
Lucifer - Heylel in the Hebrew - hêylêl, hay-lale'; from
H1984 (in the sense of brightness); the morning-star:—Lucifer.
And no marvel; for Satan himself is transformed into an angel of light. - 2 Corinthians 11:14
I believe that Lucifer and his angels once were angels who would light the thrown of God and lead worship. They know all about light and its properties. It is a trick of Lucifer to spread light in the world and darkness in the church. In accomplishing this he successfully deceives the world.
