Context: There's so many problems in our world, so much negativity. Don't worry about the darkness — turn on the light and the darkness automatically goes.

Context: Here are two kinds of light, the light on the hither side of the darkness and the light beyond the darkness. We must press on through the darkness and the terror of it if we would reach the holier light beyond.
We are here — no matter who put us here, or how we came here — to fulfil a task. We cannot afford to go of our own volition until the last item of our duty is discharged.
