What does it mean to be saved by the blood?

You may have heard the terms blood bought sanctified by the blood forgiven by the blood cleansed by the blood what does this mean to a born again Christian? At the heart of all this talk about blood it is referring to the blood that Jesus Christ shed on the cross for the remission of our sins. Some people would say that you should never mentioned the blood when speaking about the gospel but my question would be why not? Wasn't it through the death of Jesus on the cross as he shed his blood for the forgiveness of our sins? It is not some mystical kind of way of saying that Jesus Christ died on the cross for you, The Bible actually says without the shedding of blood there is no remission of sins I believe that is found in Hebrews. I think the concern comes from the fact that many people don't understand the doctrine that I'm talking about right now. In the Old Testament animals blood was shed in order to cover the sins of the people. Why wouldn't the new testament address the shedding of blood through the death of the savior? I believe there can be a false application of this verse when people talk about being covered with the blood of Jesus. They use this verse in order to gain some kind of spiritual protection from demonic forces. But the blood of Jesus isn't superstition what it represents is something very biblical. Of course we are not saved by his blood as if the actual blood of Jesus had redemptive qualities in it. We are saved when we place our faith and trust in what Jesus did on the cross by applying his sacrificial death to our own lives we are in essence saying that we have faith in what Jesus did for us on the cross but that isn't what saves us either.

What saves us is part of what I mentioned above but also by confessing Jesus as Lord. In Romans chapter 10 it says if we confess with our mouth Jesus is Lord and believe in our hearts that God has raised him from the dead we will be saved. Yes it is true the blood covers are sins but in order for the blood to cover sins we must first come to Christ confessing him as Lord. Without what Jesus did on the cross by dying for sins there would be no redemption there would be no salvation in there would be no Savior. You don't just except Jesus as your Savior you accept him as your Lord. Salvation is a personal thing when applied to the heart of man. Your mother can't save you your father can save you and neither can anyone else except what Jesus did on the cross to pay for the penalty for your sins. Part of becoming born-again is realizing that you are a sinner and repenting of your sins. Salvation is through the blood of Jesus Christ by the way. It would be a false God's gospel to except Jesus as Lord and Savior but not apply the sacrifice on the cross at the same time. Both are required, The blood and the cross. Let me reference Hebrews.

The Blood of Christ

11But when Christ came as high priest of the good things that are now already here,^a he went through the greater and more perfect tabernacle that is not made with human hands, that is to say, is not a part of this creation. 12He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, thus obtaining^beternal redemption. 13The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean. 14How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death,^c so that we may serve the living God!

15For this reason Christ is the mediator of a new covenant, that those who are called may receive the promised eternal inheritance—now that he has died as a ransom to set them free from the sins committed under the first covenant.

16In the case of a will,^d it is necessary to prove the death of the one who made it,17because a will is in force only when somebody has died; it never takes effect while the one who made it is living. 18This is why even the first covenant was not put into effect without blood. 19When Moses had proclaimed every command of the law to all the people, he took the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people. 20He said, “This is the blood of the covenant, which God has commanded you to keep.”^e 21In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies. 22In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.

23It was necessary, then, for the copies of the heavenly things to be purified with these sacrifices, but the heavenly things themselves with better sacrifices than these. 24For Christ did not enter a sanctuary made with human hands that was only a copy of the true one; he entered heaven itself, now to appear for us in God’s presence. 25Nor did he enter heaven to offer himself again and again, the way the high priest enters the Most Holy Place every year with blood that is not his own. 26Otherwise Christ would have had to suffer many times since the creation of the world. But he has appeared once for all at the culmination of the ages to do away with sin by the sacrifice of himself. 27Just as people are destined to die once, and after that to face judgment, 28so Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
