That critical spirit has a way of boomeranging. It's easy to see a smudge on your neighbour's face and be oblivious to the ugly sneer on your own. Wipe that ugly sneer off your own face, and you might be fit to offer a washcloth to your neighbour. Some of us gain a sense of or knowledge about the will of God through being exposed to His written Word. Others sort of back into it through a natural nudging of one sort or another in their conscience - some kind of 6 th sense or inclination.
Some people have more of it than others.
But the bottom line, as far as Romans is concerned, is that God will respond to us not so much on the basis of what we end up knowing , but on what we do. We all stand as sinners whose resume or CV is a guarantee of a date with the holy and just wrath of God. We're all standing on the same sinking boat, riding in the same doomed airliner. We're all involved. We're all guilty.
