Never said it is unobtainable, but that this complete perfection only comes when this corruptible puts on incorruptible and this mortal puts on immortal right before we are caught up to meet the Lord in the air. This is what you seem to not be understanding. There is a difference between willful sin and unwilful sin, but that you need to figure out for yourself as we have been trying to teach you this for a few years now, but you are to indoctrinated with "sinless perfection" which many of us have showed you is against the word of God.BTW, why do you strive for something you feel is unobtainable?
It is you, or I should say the teachings of "sinless perfection" you follow that says we are not of God's seed if we unwilfully sin.
I have nothing more to say about this with you for now.
