Just Do It!!
People are condemned not for what they don't know, but for what they do with what they know. Those who know God's written Word and his law will be judged by them. Those who have never seen a bible still know right from wrong, and they will be judged accordingly.
Let's face it, we belong to a stubborn society we want to have it our own way. We know what's right, but we insist on doing what's wrong. This passage simply tells me, I need to KNOW what is right, and live it out, JUST DO IT!!!
There are consequences for doing it MY way.
