I also would like to believe that it isn't too late for America and the rest of the Judeo/Christian west either, but increasingly I am less and less sure.
I used to consider myself an optimist, but honestly I am so fearful of this guy we have elected that I'm not even certain that America as I have known it my whole life will even survive the next few years, much less the next few decades.
Keep praying. The return of Christ and/or the arrival of the Jewish Messiah (which I believe are one and the same) may be our only hope, but never give up hope.
