When Christ instituted the New Covenant with his shed blood (Luke 22:20), He made it possible for us to be cleansed completely of sin (Hebrews 9: 13-14; 1 John 1: 7). The result was that animal sacrifices were no longer required as symbols, since Christ was the ultimate fulfillment of that symbolism. In baptism, we accept the sacrifice of Christ. Although we must still repent every time we sin, the sacrifice of Christ is applied in accordance with our repentance-no more sacrifices are needed for our sins (Hebrews 9: 24-28; 10:12).
