Salvation · The Heart of the Gospel
From the first sacrifice in Eden to the throne in Revelation, the whole Bible runs red with one theme: blood must be shed for sin to be forgiven. And at the center of it all is the blood of Jesus, which does what the blood of every lamb before it could only promise. This is what that blood means, and what it actually does.
The Question Behind It All
It can seem strange to modern ears, but Scripture gives a clear reason. God tells us plainly where the significance of blood lies:
"For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul."Leviticus 17:11 KJV
There it is: the life is in the blood. When blood is poured out, a life is given. And because "the wages of sin is death" (Romans 6:23), the only thing that can atone for a life forfeited by sin is a life laid down in its place. That is why God draws the line so starkly: "without shedding of blood is no remission" (Hebrews 9:22). Sin is not waved away or merely overlooked; it costs a life. The Hebrew word for blood, dam, and the Greek, haima, run all through Scripture precisely because the whole plan of salvation turns on a life given for ours.
Written in Shadows First
Long before the cross, God taught His people the meaning of blood through pictures. On the night of the Passover in Egypt, He told Israel to kill a lamb and put its blood on their doorposts, and He promised, "when I see the blood, I will pass over you" (Exodus 12:13). The blood on the door was the difference between death and life. Every year the sacrifices, and especially the Day of Atonement, drove the lesson deeper: sin brings death, and only substituted blood covers it.
But those animal sacrifices could never truly finish the job; "it is not possible that the blood of bulls and of goats should take away sins" (Hebrews 10:4). They were promissory notes, shadows pointing to one coming sacrifice that would be enough. That is why John the Baptist saw Jesus and cried, "Behold the Lamb of God, which taketh away the sin of the world" (John 1:29). The true Lamb had come.
Not Just Any Blood
The reason the blood of Jesus is infinitely greater than any lamb's is who He is. Peter calls it "precious":
"Ye were not redeemed with corruptible things, as silver and gold... but with the precious blood of Christ, as of a lamb without blemish and without spot."1 Peter 1:18–19 KJV
He was the spotless Lamb, sinless, so His life was not forfeit for His own sin and could be given fully for ours. And here is the truth that lifts this above every other sacrifice, and that is pure gospel: the One whose blood was shed is God Himself, come in flesh. Paul told the elders to shepherd "the church of God, which he hath purchased with his own blood" (Acts 20:28). His own blood. The blood that bought us is the blood of God manifest in the flesh, which is why it can do what oceans of animal blood never could.
The Heart of the Study
The New Testament heaps up what this blood accomplishes. Read the list slowly; every line is something the blood does for those who are under it.
| The blood of Jesus... | Scripture says... |
|---|---|
| Redeems us (buys us back) | "In whom we have redemption through his blood" (Ephesians 1:7) |
| Gives remission of sins | "my blood... shed for many for the remission of sins" (Matthew 26:28) |
| Justifies us | "being now justified by his blood" (Romans 5:9) |
| Cleanses us from all sin | "the blood of Jesus Christ his Son cleanseth us from all sin" (1 John 1:7) |
| Brings us near to God | "ye who sometimes were far off are made nigh by the blood of Christ" (Ephesians 2:13) |
| Makes peace with God | "having made peace through the blood of his cross" (Colossians 1:20) |
| Is our propitiation | "a propitiation through faith in his blood" (Romans 3:25) |
| Seals the new covenant | "This cup is the new testament in my blood" (Luke 22:20) |
| Sanctifies us | "that he might sanctify the people with his own blood" (Hebrews 13:12) |
| Gives us victory | "they overcame him by the blood of the Lamb" (Revelation 12:11) |
Look closer at three of those words, because they open up treasures. "Redemption" is the Greek apolutrosis, the buying back of a slave out of bondage by paying a ransom (lutron); the blood is the price that purchased our freedom. "Remission" is aphesis, which means a release, a sending away, a letting go, your sins are not just covered but carried off. And "propitiation" in Romans 3:25 is hilasterion, the very word the Greek Old Testament used for the "mercy seat," the golden lid of the ark where the atoning blood was sprinkled once a year. Paul is saying Jesus Himself is now the mercy seat, the meeting place where the blood satisfies God's justice and mercy is extended to us. Even "cleanseth" in 1 John 1:7 is katharizei, a present-tense word: the blood keeps on cleansing those who walk with Him.
Where It Lands
Here is the truth that turns all of this from information into salvation. On the night of Passover, it was not enough that the lamb was killed; the blood had to be applied to the doorposts of each home. A family with a slain lamb but an unmarked door was not protected. The blood had to be put where God said to put it. In the same way, the blood of Jesus has been shed for the whole world, but it saves those to whom it is applied.
So how is the blood applied to you? By obeying the gospel it purchased. Notice that the blood was shed "for the remission of sins" (Matthew 26:28), and then hear how Peter told convicted sinners to receive that very remission: "Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost" (Acts 2:38). The same remission the blood bought is applied to us as we repent and are baptized in Jesus' name, calling on Him, and the Spirit seals it. This is why baptism is "in the name of Jesus," His is the name, and His is the blood, that saves. Revelation pictures the redeemed as those who "washed their robes, and made them white in the blood of the Lamb" (Revelation 7:14). Do not merely admire the blood from a distance. Come and get under it, God's own blood, shed for you, applied to you, cleansing you from all sin.
For You
If you have never come under the blood of Jesus, that is the most important thing you will ever do. No amount of good living can pay the wage that sin owes; only His blood can. Come to Him in repentance, be baptized in His name for the remission of your sins, and receive His Spirit. Let the precious blood be applied to the door of your life.
And if you are His already, live in the good of it. When the enemy accuses you, or your own heart condemns you, do not argue in your own strength; the saints "overcame him by the blood of the Lamb, and by the word of their testimony" (Revelation 12:11), and so can you. Plead the blood that has already justified you, keep walking in the light where its cleansing flows, and remember that the God who bought you with His own blood will never undervalue what He paid so dearly to redeem.
