"'It is finished.' That to which so many types looked forward, that which so much in the tabernacle and its ritual foreshadowed, that of which so many of God's prophets had spoken, was now accomplished. A covering from sin and its shame--typified by the coasts of skin with which the Lord God clothed our first parents--was now provided. A more excellent sacrifice--typified by Abel's lamb--had now been offered. A shelter from the storm of divine judgment--typified by the ark of Noah--was now furnished. The only begotten and well believed Son--typified by Abraham's offering up of Isaac--had already been placed upon the altar. A protection from the avenging angel--typified by the shed blood of the Passover lamb--was now supplied. A cure from the serpent's bite--typified by the serpent of brass upon the pole--was now made ready for sinners. The providing of a life giving fountain--typified by Moses striking the rock--was now effected."
Glory to God for the finished work of Jesus! The work is accomplished and we need not-indeed, we must not-add anything to it.
