If you don't want your kids to grow up and be saved, you need to make sure that church is just a performance. You need to make sure that every Sunday you're just putting on an act and just going through the motions and make sure your kids know it. Make sure you're a different person on Monday because before you know it they will start hating going to church, they'll hate who you are on Sundays, and church will be drudgery.
