"But the one who does not know and does things deserving punishment will be beaten with few blows."
Doesn't this just speak to you! Think about it from a drunk drivers point of view. He broke the law and deserves punishment. But it gives a real picture of what sin does. How? It shows us that wrong is wrong whether we know it is or not. Right and wrong is not relative, it doesn't depend on how a human feels. It doesn't matter whether we feel that what we do is wrong it matters whether it IS wrong. So how do we know? You may ask: "Is cussing really wrong?" "Is drinking beer wrong?" "Is leaving flaming bags of dog poo on a doorstep wrong?" How do we determine what is wrong? I have one question, who gave you that job? To know what is truly right is to know God. He determines right from wrong. Need a good place to start try Exodus 20. It is more commonly known as the 10 Commandments. Oh I must warn you that there are consequences for doing wrong. The least is embarrassment; the worst is never knowing God.
Moral of this Story: Avoid being "beaten with few blows."
