The same way the sun, moon, earth, stars, and angels (none of whom are 100% pure in the sight of G-d) do.
I'm sorry my words were too feeble to make my point, but I stand by my position. G-d never demanded a perfection of which no created thing is even theoretically capable. He demands that we each do our part to perfect the world in the Kingdom of the A-mighty. Every single deed we do in life, good or evil, is judged and somehow recompensed. Life is not about being saved or going to Heaven. It's about obeying G-d down here where our souls were sent from Heaven. The idea that the slightest imperfection calls for either damnation or salvation by the "messiah" is a straw man.
If you were to read a Jewish prayerbook you would not read many prayers asking to be taken to Heaven. You'd read prayers for food to eat, clothes to wear, time to study the mysteries of the Torah, long life to see the Days of Mashiach and the World to Come, the restoration of the Temple Service, the restoration of the Davidic Kingdom, etc.
It is not for you to finish the work, but neither are you free to withdraw from it.
Besides, for fifteen hundred years chr*stianity merely replaced the "works of the law" (from the Bible) with its own "works of the law" adopted from surrounding pagan cultures. That was better . . . how???
The sun, moon earth, stars, and angels will not be judged by G*d.
It doesn't matter WHAT good works we do here on earth, not that we shouldn't strive to do as many as we can, they would almost invariably not be enough to make ourselves worthy to stand before G*d.
We can NEVER do enough good works to justify us in G*d's sight.
It is a gift that G*d offers that we have to accept.
The angels still in heaven have not sinned. They may not be perfect but they haven't sinned.
The angels that sinned, Lucifer for example, were thrown out of heaven.
I agree that we should obey G*d here on earth and do our best to make the earth a better place.
Everything we do here on earth will be judged. If we did not have an intercessor we WOULD be damned for eternity. Not necessarily to Hell but not with our Heavenly Father either, and that could be just as bad.
It is not imperfection that damns a person. It is sin without payment. Payment cannot be made unless the gift is accepted.
I'm not sure I understand your last statement.
If you would care to amplify I might be able to respond.
