Psalm 139:11-12

If I say, “Surely the darkness shall cover me,
     and the light about me be night,”
even the darkness is not dark to you;
     the night is bright as the day,
     for darkness is as light with you.
(ESV)

There have been times in my life where I have wanted the darkness to surround me and the light to be gone.  Sometimes it was because of things that I wanted to do, so I didn't want to be seen by God. I wanted Him to vacate the premises so that I could do what I wanted without Him standing over my shoulder.  There have been other times that I simply wanted to dwell in my own misery.  I didn't want Him there to bring that ray of light, I wanted to "enjoy" my pitiful state... It seemed easier.

In those times I don't always see God bursting through.  And notice that it doesn't say that He comes bursting through, vanquishing the darkness.  It only says that it isn't darkness to Him.

We are such great fools that say in our hearts, "There is no God..." Here.
