Light is a universal understanding about the Divine, and darkness is likewise an understanding but of being far from the awareness of God, in the dark, not in the know.
Scientifically, spiritually, metaphysically Light is the glorious ignition of creation. The big bang/flash, in the beginning, in the whirling atoms, Light, mystical experiences, writings of the illumined -- all point to Light.
In Christianity, we are called to be the light of the world, to let our lights shine, to get out from under our bushel baskets.
We were also told of a great measuring stick - by the fruits we shall know. The result reeks of the origin.
The fruits we seek, when we live as best we can in and as Light, are the fruits of the Spirit, and as Jesus boiled it down, love.
Today is the day to sincerely look at ourselves and our fruits and just check out how Lightfilled they have been up until now. Then to take courage and redirect any parts of ourselves that are not in Light, not creating Love, but creating murky or even dark results. We know if we will just admit to ourselves, because The Light dwells within us.
Lord, I open myself to fully embrace and express Your Light. Flow away all darkness in me and lead me to live in such a way as to produce the fruit of love in every corner of my life. I throw open the windows of my being and welcome Your Light to shine fully in me. I am Yours.
