According to Ezekiel’s vision, in the center of the temple courtyard there stood an altar on which sacrifices were to be made. Since the period of grace began, after Jesus’s death and resurrection took place, it has seemed as if sacrifices are no longer necessary. What we can assume from the appearance of an altar in the new temple is that there will come a time when salvation by grace will no longer be available to mankind. In other words, God’s law will once again be the standard by which all men will be judged (Ezekiel 43:27). Although Jesus’ death paid the penalty for every sin that ever had or would be committed, our ability to claim that payment and apply it to our spiritual account has an expiration date, the day he establishes his kingdom on earth.
During Christ’s millennial reign on earth, a new world order will exist that requires submission to God’s will. Obedience to God’s laws will no longer be optional. If you can image a kingdom in which there will be no sins committed against God, you will understand that God’s sovereignty has never been forced upon man up to this time. Free will represents the ability man has to rebel against God. There will come a time when man’s free will is exempted and God’s grace will cease to exist in the sense that it can no longer be claimed in lieu of obedience to the law. Therefore, sacrifices will be made to God just as they were when the first temple was built by king Solomon. At that time, the celebration of feasts signified a right relationship between God and his people. In the future, that relationship will be restored and it will cause the people to do what was never possible before, live according to God’s commandments.
A glimpse into this future new world order is given in Hebrews 13:10-21. It says:
We have an altar, whereof they have no right to eat which serve the tabernacle. For the bodies of those beasts, whose blood is brought into the sanctuary by the high priest for sin, are burnt without the camp. Wherefore Jesus also, that he might sanctify the people with his own blood, suffered without the gate. Let us go forth therefore unto him without the camp, bearing his reproach. For here we have no continuing city, but we seek one to come. By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name. But to do good and to communicate forget not: for with such sacrifices God is well pleased. Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give an account, that they may do it with joy, and not with grief: for that is unprofitable for you. Pray for us: for we trust we have a good conscience, in all things willing to live honestly. But I beseech you the rather to do this, that I may be restored to you sooner. Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant, make you perfect in every good work to do his will, working in you that which is well pleasing in his sight, through Jesus Christ; to whom be glory for ever and ever. Amen.
