Be careful of the books you choose, consider them as company you keep. For they will influence your family's habits and character.
Do you ever read something that really resonates within you? I don't have family to worry about when I choose what to read (the cats aren't big readers) but I do need to look to myself. I've noticed that I'm very susceptible to the atmosphere of my reading. If I'm reading secular chicklit about a girl's racy life I want that life too. Little House on the Prairie has me reaching for the broom to sweep the kitchen. I guess I have too much imagination but that's the way I am and I'm deeply affected by what I read. Impressionable. That's the word, I think. I am very impressionable.
I already avoid chicklit and also most fantasy and magical realism as these all send me in directions I don't want to go. But I don't read exclusively Christian titles although I try and avoid anything glorifying attitudes and actions that are contrary to Christian belief. Is this enough? Because you can't always tell where a story is going to take you from the blurb on the back.
I need to think more and listen. If God wants me to change my reading habits then he won't be silent.
