Stanley’s little book (less than 100 pages) is fantastic for people who are searching to know and understand God, whether they’ve never been to church before or if they’ve been “saved” for a long time. He breaks down the commonly-held view that adherence to things like the Ten Commandments and overall morality will assure us a place in heaven.
We instituted a policy with our girls, though we’re not always consistent with it, that whoever hits back will receive a harsher punishment than the original offender. She who retaliates will get a longer timeout. The words, “But she hit me first,” were all the confession we needed. (In this system I guess you’re better off striking first.) This is an attempt to help them see that our hearts, darkened as they are with sin, are bent towards revenge.
