God who exists outside of time and reigns in Eternity (no change nor entropy in the Trinity) created all that is. With His words "Let there be light" He started the clock and balanced the equation.
He is the source of all light and the assigner of a 3 x 108 m/s velocity to light.
Unchanging, pure unapproachable Light is the source of space-time/matter. Jesus Christ is the Light of the World through whom all things were made.
Sincerely yours in Jesus through Mary,
Become like Jesus
Live for the Triune God
Seek the Light of Our Lord Jesus Christ
See you on the High Ground!
