• Jesus' blood is the blood of the covenant (Mt 26:28) - shed in sacrificial love, it seals once and for all the eternal covenant between God and his people. It fulfills and surpasses the Old Covenant, sealed with the blood of oxen (Ex 34:3-8).
  
  
• Makes atonement for sin (Rom 3:25; Heb 9:11-28), forgives sin (Eph 1:7; 1 Jn 1:7, Rev 1:5), redeems us (1 Pet 1:18, Ac 20:28, Rev 5:9), justifies us (Rom 5:7), reconciles us to God (Col 1:20). It fulfills the Old Testament blood sacrifices (Lev 1:5, 11; 16:11-12).
  
  
• Sanctifies us, makes all our works holy and pleasing to God (Heb 13:12, Rev 7:14).

• The blood of Jesus cleanses our consciences (Heb 9:14; 10:2, 14). The Old Covenant purification by blood of bulls and goats was partial and provisional; there was still a conscience burdened by sin. How much more is the blood of Christ: its cleansing is interior, deep and total. Our sins are finite; the value of his blood is infinite! (1 Pet 1:18f). If only we realized how cleansed our consciences are, how God has cast our sins from us as far as East is from West! (Ps 103:12).
  
  
• Gives us confidence of access to God (Heb 10:19-22, Eph 1:13). "Therefore, we have boldness to enter" (Heb 10:19). Previously only the high priest could approach God, only once a year, and only with blood. We should never think our unworthiness or sins can keep us from full access to the all-holy, all-merciful God (that only comes from thinking we could make ourselves worthy if only we were better).
  
  
• Equips us to serve God (Heb 13:20). No matter what our natural talents or failings, we are all equipped!

• The blood of Jesus conquers Satan - we can claim the blood with authority against our adversary. The blood prevented the Destroying Angel from entering the Israelite homes marked with blood (Exod 12:21-30; Heb 11:28).
  
  
• Robs Satan of any grounds on which to accuse or condemn us (Rev 12:11).

Just as our blood (white blood cells) fights off germs which attack the body, so the blood of Christ is a weapon against the enemy who attacks his Body.
