As night falls, no moon takes the sun's place. Working by candlelight only heats up my hot, muggy apartment. Sleep becomes problematic, because no breeze moves the sultry air. But I know that its best to stay in bed. Walking around in the dark threatens my toes.
Some people live that way from a spiritual perspective.
They choose to remain in darkness. Perhaps one problem is that we Christians prefer to criticize the dark rather than reflect the light. We tell non-Christians how bad their lives are, but we neglect to tell them how a personal relationship with God through Jesus Christ can transform their darkness into light. I'm not saying we should tolerate evil practices. But that should not be all we talk about.
