The sacrificial [red] heifer was conducted without the camp and slain in the most imposing manner. Thus Christ suffered without the gates of Jerusalem, for Calvary was outside the city walls. This was to show that Christ did not die for the Hebrews alone, but for all mankind. He proclaims to a fallen world that He has come to be their Redeemer and urges them to accept the salvation He offers them. The heifer having been slain in a most solemn manner, the priest, clothed in pure white garments, took the blood in his hands as it issued from the body of the victim and cast it toward the temple seven times....
The body of the heifer was burned to ashes, which signified a whole and ample sacrifice. The ashes were then gathered up by a person uncontaminated by contact with the dead and placed in a vessel containing water from a running stream. This clean and pure person then took a cedar stick with scarlet cloth and a bunch of hyssop, and sprinkled the contents of the vessel upon the tent and the people assembled. This ceremony was repeated several times ... and was done as a purification from sin.
Thus Christ, in His own spotless righteousness, after shedding His precious blood, enters into the holy place to cleanse the sanctuary. And there the crimson current is brought into the service of reconciling God to man. Some may look upon this slaying of the heifer as a meaningless ceremony, but it was done by the command of God and bears a deep significance that has not lost its application to the present time....
The blood of Christ is efficacious, but it needs to be applied continually....
If it was necessary in ancient times for the unclean to be purified by the blood of sprinkling, how essential for those living in the perils of the last days, and exposed to the temptations of Satan, to have the blood of Christ applied to their hearts daily. FLB 200
Daily it will be their prayer that the sanctification of the Sabbath may rest upon them. Every day they will have the companionship of Christ and will exemplify the perfection of His character. Every day their light will shine forth to others in good works. Pr 161
For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God? Hebrews 9:13-14 (King James Version)
