Deeds done in the dark tend to be dark deeds

One of the first signs that you may be doing something you shouldn't be doing is if you try to keep it a secret. ... keeping something secret is hiding because you're ashamed of what you're doing, you don't want people to know and you seek to cover up what you're doing or to hide. ... The first thing that Satan does when we've sinned is to tell us to hide. "Hide. Cover it up." He knows that if we hide that we are not seeking the Lord and we're not seeking light.

It's a good rule to live by. And with adults, it's the same thing. The scriptures say, "Anytime that you endeavor to hide your sin..." There's Adam and Eve in the garden. One of the first things, the first impulse is quick, run, hide. Instead of seek the Lord. Go to the Lord for refuge. The Lord can cleanse you and heal you. Satan knows that that is the pathway to freedom and joy, so he doesn't want us to do that. He wants us to stay in chains and bondage of sin. The only way to do that is to hide and to stay away from the source of light and truth.
