"Then I shall sprinkle pure waters upon you, and you shall be clean, from all your uncleanness, and from all your idols, will I cleanse you. I will also give you a new heart, and I will place within you a new spirit... " (Ezekiel 36:25-26)
In our own times, the commandment of the red heifer takes on more and more significance. For without it, the Divine service of the Holy Temple cannot be resumed. There is a spiritual renaissance today in Israel; after almost 2,000 years, Israel is clearly moving towards the time when the Holy Temple on Mount Moriah - the prophesied Third Temple - will be rebuilt.
More and more Jews are returning to the Torah, to the God of Israel and the ways of our fathers. And more and more are beginning to realize that the Holy Temple is the only solution for achieving the elusive peace we all desire to see: for the Creator Himself, the Supreme Author of peace, has stated: "The honor of this last house will be greater than that of the first, says HaShem of Hosts; and in this place I will grant peace, says HaShem of Hosts" (Haggai 2:9).
