Well, I think it’s nice that you’re not on the side of such folks who construe it that we are perfecting the world through our flawed living out of Christianity! LOL.
Scripture teaches time and again that man corrupts things that he touches. The early church fathers recognize this and this is the reason we have the Bible. While the Holy Spirit now endwells Christians to assist us in living our lives (not a small issue), we are still under a curse until we're redeemed through death or Christ's return.
