When should we expect Moshiach to arrive? What should be the basis of our faith in his arrival?
An answer can be found in this week's portion where we read about the prohibition against a kohen drinking wine before entering the Holy Temple. According to the Rambam, this prohibition stands today, which means that Moshiach can arrive with a fully functional Temple in less than twenty-four minutes.
