I do not understand how evil walks in the day, should it not fear the light?

the personification of evil is light.
"lucifer" means light.

Stop watching the 700 Club. That will resolve a lot of your fears.

actually...it means "shining one, morning star"

well corrected, thankyou

it can also mean candle.

either way, it's still light as opposed to dark.

ghosties, ghoulies, hobgoblins and other evil creatures come out on the cusp, so to say, wherever there is an interstice in time. The dangerous times are dawn because it's no longer night and not yet day; at dusk, for the same reason; at noon when it's no longer morning but not yet quite the afternoon either; and, of course, at midnight when this day isn't quite over but the new day has not yet come.

Keep studying the ancient lore and you'll see I'm right. It's why crossroads are the most dangerous places and boundary lines between estates or counties or towns. Any grand master of asinine arcana could tell you that.

Evil doesn't lie in the night, anymore than in a snake or shark. It's lie in the grey matter of humans.
