The Day of Atonement is full of symbolism which points to the ministry and work of Jesus Christ. The purpose of the atoning sacrifice was to provide a covering for sin, but God wanted to take their sin away. The author of Hebrews states that the laws and rituals were "a shadow of the good things to come, not the very image of the things." He further stated the rituals and sacrifices which had to be performed year after year could not make one perfect, nor could they take away sins. But concerning Christ, the writer said that "we are sanctified through the offering of the body of Jesus Christ once for all. And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: but this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God." (read chapters 9 and 10 of Hebrews).
One of the most important principles gleaned from the Passover account was that the blood identified God's people, and distinguished them from the Egyptians. Today, as then, the blood of Christ is what separates us from the world and spares us from judgment. Peter wrote in his first letter, "Forasmuch as ye know that ye were not redeemed with corruptible things.... but with the precious blood of Christ, as of a lamb without blemish and without spot: who verily was foreordained before the foundation of the world, but was manifest in these last times for you." (1 Peter 1:18-20).
