 A little bit of hidden and secret sin in our lives when there's things that we press back into the outer recesses of our minds so that no one knows except for us. The thing that kind of creeps up when the doors are closed and the windows are shut and no one's around. The things that we think about, the things that we do, like that little bit of sin. You say, well, it's not hurting anybody. God's word says differently.
