So you do believe in light of Bible prophecy that it would fail then?
I believe that Biblical prophesy says we will degenerate into a cesspool and be "governed" by tyrants, so there is a good chance that a civil war would fail. I'm not saying that the good shouldn't oppose the bad, but we will never defeat Evil else He would not have told us how He is going to come back to do that job. I used to be a fight evil at every turn person, but the more I look at Biblical prophesy and talk with other who are grounded in the Bible, the more conflicted I become between my Human instincts and the Spiritual realm. I suppose that is the way it should be - our very humanity is a conflict with His holiness. Paul lamented that he did that which he would not do and did not do that which he would do. He understood that his humanity made him incapable of being 100% obedient and that was after meeting the risen Jesus on the road. If those that had actual contact with the living and the risen Jesus retained their human failings, the best we can do is to recognize and repent. Hence the saying, "The poor in spirit will inherit the kingdom of Heaven" - we will remain sinful in nature even after He washed away our sins and considers us holy and pure. Praise Him for His Love! God Bless.
