We continue in Jesus’ description of last things, and what we find is that, while there were some things the earliest Christians could go off of to anticipate the fall of Jerusalem, for modern Christians we are given very little.  The return of Christ will be sudden, cataclysmic, and mostly unexpected.  Jesus leaves us with the stark warning that with his return will come the Final Judgment, and so in all things we should be like a servant at the ready.
