Prepare how for his return????
By going to church and reading the Bible and doing good works?
We should always be doing that, but preparing for his return is just what it means....Just as you would prepare for a vacation or any place you were going...
Jesus gave us *Signs and Seasons* for a purpose, not just to hear himself talk...
By preparing ourselves as the wise virgins did. By making ourselves conform to His commandments. By following the exhortations of Paul that we run the race to the end.
We are not supposed to listen to modern day astrologers give us spiritual advice any more than the Jews were supposed to listen to astrologers in Deuteronomy. And I consider the Harold Campings of this world to be modern day astrologers.
