Read Hebrews 9.
Hebrews 9 continued the argument that Christ was better than the Old Testament sacrificial system. The author of Hebrews presented a tight argument comparing the sacrificial system under the old covenant (vv. 1-10) and the new covenant Christ has set up and mediated (vv. 11-28).
The key point of this chapter is that Christ’s death on the cross accomplished the new covenant. The blood of his sacrifice was offered in heaven not on earth (vv. 11-14) and it purified everything, including us (vv. 15-28). This is why the sacrificial system revealed by Moses is no longer necessary. Christ’s redemption was better and brought that old system to an end.
One of the key takeaways from this chapter for us is that Christ’s death accomplished something for us spiritually that the animal sacrifices of the Old Testament law never could. In verse 13 the author of Hebrews mentioned that the blood from those animal sacrifices had to be sprinkled on the people to make them ceremonially clean. That process was described in Numbers 19 and was used on someone who touched a dead body.
But in verse 14, the author of Hebrews argues that the blood of Christ removed the works of death from our consciences. In other words, it gives us true relief from the guilt of our sins.
Yes, it is true that “the wages of sin is death” (Rom 6:23) but Hebrews 9:14 says that Christ’s death cleanses our conscience from those works that lead to death (in other words, sin).
Are you tormented by guilt for the sins you’ve committed in your life? Don’t be! Not because they were not wicked but because, if you are in Christ, they are fully forgiven. Your past has been redeemed in him so now you have the freedom of conscience to live and serve the Lord.
