Psalm 139:11–12 (ESV)

11 If I say, “Surely the darkness shall cover me, and the light about me be night,”

Even fleeing into the darkness does not help a person to run away from God. For the all-seeing God, the densest darkness is as a clear light. 1 John 1:5b says, God is light, and in him is no darkness at all. He lights up the darkness. That was already evident in creation. In Genesis 1:3–4 we read, And God said, Let there be light, and there was light. And God saw that the light was good. And God separated the light from the darkness.

God is light and therefore Jesus, Son of God, could say, I am the light of the world (John 8:12; compare with John 12:46). He immediately added, Whoever follows me will not walk in darkness, but will have the light of life (John 8:12).

This beautiful promise can stop us from saying, Let the darkness engulf me. It would not help us anyway, as God sees us there also. But especially, he wants us to be walking in the light.

And later, on the new heaven and the new earth, it will be God’s light that will shine gloriously and that will beneficially surround us (see Revelation 21:23, and Revelation 22:5).
