Let us first of all understand that there is nothing in the Bible demanding a red heifer to be born prior to the return of Jesus Christ. It is true, however, that some Jews and Christians have attached an end-time application to the ancient Old Testament ritual of the killing of a red heifer for purposes of purification. As will be explained herein, this ritual is no longer in force. But some Jews and Christians believe that the ritual must be applied today, as a prerequisite for the commencement of sacrifices and the building of a third temple, and they expect a red heifer soon to be born. (In fact, when conducting a Yahoo search on the Internet, one receives about 280,000 results for "red heifer.").
"You are the light of the world. A city that is set on a hill cannot be hidden."
