These seems like a very interesting topic to me. Also I believe it's not as simple as other subjects that we have learn around here, there are topics that take a lot more than just a few moments of contemplation and meditation.
Of course to the pure all things are pure, because he is pure. But whom do you know here on earth that is PURE, ALL CLEAN, NO mistakes never...? We only know about Jesus.
Now, Since our minds tent to make shortcuts to bring faster answers to our daily challenges, it's usual that we don't give a deeper thought to the fact that all people have many different and specific degrees of wrongness, compassion, evil and ignorance. There are people who are a little greedy, greedier, very greedy, and EXTREMELY GREEDY and the same goes with vanity, envy and selfishness.
On the same way there are people with different degrees of purity. I once hear that Ray said that there is a point we can reach when sin doesn't control us anymore, a place where we are no longer slaves of sin. Of course that even the most pure of all humans still make mistakes (in comparison to God, the light of the purest human is darkness), but the mistakes of someone like Paul are little in comparison with everything that he was able to accomplished (it's like when writing a masterpiece, a few grammar mistakes doesn't take the magnificence of the work at hand or the truthfulness of the statements on it), generally saying we could pretty much tell that Paul was pure, even so he wasn't 100% pure here in the flesh while he was still alive, since no none is good.
As Dennis well said on another tread a little while ago:''Our judging is going to be individualized by God'' and it's going to be in according with OUR OWN acts. Not in according to the acts of your country, your family or friends, we are not going to be judged in groups, if you live around people whom are pure that doesn't make you automatically pure (neither the other way around.)
At the end of the day, what God takes in account the most is our main intentions and motivations that come out from our heart, this is why we must worry not so much about the physical but about the spirit in which we do everything we do.
Once we start to watch and realize (very consciously) that there are so many different levels and degrees of evil and purity, a whole new panorama will open to us.
I know what I am saying is so obvious and logical, but since we have been brain washed by the church so badly, we need to give these a deeper thought. The protestand church used to say that when deciding you eternal destiny, the levels of evil doesn't matter, that if you just didn't accept Jesus as your personal saviour with a magical prayer, then that is a reason enough to get toasted for a little bit more than just a few hours in a place in spanish called ''Infierno'' (when you pronounce it sound even more creepy).
Think about it, not all Christians or pastors have the same level of wrongness and ignorance. There will be more judgement to the ones that knowing that something is wrong, they still do it. However, we don't always have it all right at the first intent. I have felt the judgement, I am guilty of doing things even when I know that these are of no convenience for me, but I ask forgiveness, and I keep trying, and get up again and again, until God, using time and hard experiences finally makes me overcome my past mistakes. I don't have it all figure it out yet, but I keep running forward, just running forward...
But to those who are defiled and unbelieving, nothing is pure, but both their mind and their conscience are defiled. They profess to know God, but by their deeds they deny Him, being detestable and disobedient, and worthless for any good deed."
And whom are the ones that profess to know God? I remember when I was detestable and disobedient and worthless for any good deed on a great degree...
