You shall also make a plate of pure gold and shall engrave on it, like the engravings of a seal, “Holy to the Lord.” You shall fasten it on a blue cord, and it shall be on the turban; it shall be at the front of the turban. It shall be on Aaron’s forehead, and Aaron shall take away the iniquity of the holy things which the sons of Israel consecrate, with regard to all their holy gifts; and it shall always be on his forehead, that they may be accepted before the Lord. – Exodus 28:36-38
When God gave Moses the instructions on how Israel’s high priest was to be clothed, He included a gold plate to be worn upon his forehead. Upon the plate was engraved the words, “Holy to YHWH.” It spoke of the consecrated status of the man who served and defined his position as the representative of the entire Israelite nation, giving him the ability to present blood sacrifices on their behalf. The high priest was the only person on earth able to stand before God and perform this service.
Jesus Christ, our Savior, was set apart in eternity past to bear our guilt before the Father. The striking difference was that at the appropriate moment in (the fullness of) time, He became our sacrifice. Of course, it was not the blood of an animal that our Savior brought, but His own and there was no need for any outwardly engraved sign for He bore the truth in His own life and body.
Israel’s acceptance before God was completely wrapped up in the work of its great high priest and, as it was with him, our acceptance before the Father remains completely wrapped up in Jesus, the Messiah. All that remains is for a person to admit sin, believe He died for it, and agree that He is his or her Savior and Lord. The moment this occurs is the pivotal moment of acceptance.
No man is excluded from calling upon God, the gate of salvation is set open unto all men: neither is there any other thing which keeps us back from entering in, save only our own unbelief. – John Calvin
