One of the more obvious changes Jesus made in bringing the Old Covenant laws to their maturity is with regard to sacrifice and worship. The New Testament tells us, particularly in Hebrews 9:7-15, that Jesus' sacrifice on the cross fulfilled everything the animal sacrifices were meant to do but really couldn’t. They were necessary for the time being, but imperfect. The Old Covenant sacrifices enabled the worshipper to “draw near” to God. But even then, the people were separated from God by the veils of the Temple and access to God was mediated by the priests, who were the only ones who could enter the Holy place and the Holy of Holies. Because of Jesus' sacrifice, now worshippers draw near to God through faith in Christ with no earthly mediator. Every worshipper has full access to the presence of God.
The animal sacrifices are now rendered meaningless because of Jesus. However, worshippers still do bring sacrifices to God. The sacrifices of the New Covenant are the sacrifices of praise and thanksgiving. In Romans 12, the worshipper himself is called a living sacrifice, implying that our whole lives are to be an acceptable offering to God in Christ. In Christ, we “draw near” to God with full assurance and the Spirit of God dwells in our hearts, not behind the veil of the Temple and the maturing of the Temple is what we’ll discuss next.
