What is darknes to God?

Excerpts from Psalms:

Chapter 139 "...If I say, surely the darkness shall cover me...the darkness and the light are both alike to thee."

Chapter 112:4 "Unto the upright there ariseth light in the darkness.."

Chapter 18 "..darkness was under His feet...the Lord my God will enlighten my darkness.."

and...

Luke 1:79 "To give light to them that sit in darkness..."

My MOST favorite Psalm for all my life has been Psalm 27:

"The Lord is my light and my salvation: whom shall I fear? the Lord is the strength of my life; of whom shall I be afraid?

When the wicked, even my enemies and my foes, came upon me to eat up my flesh, they stumbled and fell.

Though a host should encamp against me, my heart shall not fear: though war should rise against me, in this will I be confident.

One thing have I desired of the Lord, that will I seek after: that I may dwell in the house of the Lord all the days of my life, to behold the beauty of the Lord, and to inquire in his temple.

For in the time of trouble he shall hide me in his pavillion: in the secret of his tabernacle shall he hide me: he shall set me up upon a rock.

And now shall my head be lifted up above my enemies round about me: therefore will I offer in his tabernacle sacrifices of joy; I will sing, yes, I will sing praises unto the Lord.

...I had fainted, unless I had believed to see the goodness of the Lord in the land of the living.

Wait on the Lord: be of good courage, and he shall strengthen your heart: wait, I say, on the Lord."
