God said, Let there be light; and there was light. And God saw that the light was good (suitable, pleasant) and He approved it; and God separated the light from the darkness. Genesis 1:3-4 (AMP)
Pay attention here. Light (which is good) was created by God. Darkness (which is lacking good) was not created, just separated from the light.
In the same way, good was created, while evil was not created, it is just a lack of good. You can't fight evil with evil. You fight evil buy shining your goodness upon it.
If you bring a lamp into a dark room, what happens? Does the lamp get darker or the room get lighter?
True Light SHINES, and doesn't wait for darkness to pass it over.
Be the Light!
