At one time in the history of the West, virtually everybody knew the Bible. The similes in the title of this post were so widely used and understood that they have come down to us as cliches.
Similes and metaphors are vital to humans. We understand a new thing only by comparing or contrasting it to some already known thing. Yet we come into the world from darkness, with vague sensations of a world wider than the womb. That there is light must be the original knowledge. Even this, we could not grasp unless we had known the gestational darkness.
Before creating the sun in Genesis 1, God spoke light into existence. It is the light of wisdom by which we see everything else.
Be sure the similes and metaphors in your writing are as crisp as an October morning. Give your reader just enough sun in the beginning to keep him reading even after the sun sets.
