“And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.” (Revelation 12:11)
This is the last reference in the Bible to the shed blood of the Lord Jesus Christ; here, it is the overcoming blood, enabling believers to withstand the deceptions and accusations of Satan.
There are at least 43 references to the blood of Christ in the New Testament, all testifying to its great importance in the salvation and daily life of the believer. Judas the betrayer spoke of it as “innocent blood” (Matthew 27:4), and Peter called it “the precious blood of Christ, as of a lamb without blemish and without spot” (1 Peter 1:19). It is the cleansing blood in 1 John 1:7 and the washing blood in Revelation 1:5, stressing that it removes the guilt of our sins.
Paul calls it the purchasing blood in Acts 20:28 and the redeeming blood twice (Ephesians 1:7; Colossians 1:14; see also 1 Peter 1:18-19; Revelation 5:9), thus declaring the shedding of His blood to be the very price of our salvation. Therefore, it is also the justifying blood (Romans 5:9) and the peacemaking blood (Colossians 1:20). Its efficacy does not end with our salvation, however, for it is also the sanctifying blood (Hebrews 13:12). There is infinite and eternal power in the blood of Christ, for it is “the blood of the everlasting covenant” (v. 20).
The first reference in the New Testament to His blood stresses this aspect. Jesus said at the last supper, “This is my blood of the new testament [same as ‘covenant’], which is shed for many for the remission of sins” (Matthew 26:28). Let no one, therefore, ever count the “blood of the covenant…an unholy thing” (Hebrews 10:29), for the blood of Christ is forever innocent, infinitely precious, perfectly justifying, always cleansing, and fully sanctifying.
