In 1 John Chapter 5. verse 6. We see a statement that the Holy Spirit and the blood of Jesus. Can not be separated, in other words you can not have one without the other.
Verse 6. This is the one who came by water and blood. Jesus Christ not with water only, but with water and with blood. And with the blood it is the spirit who testifies, because the Spirit is truth.
There you have it in scripture written in truth and in the Bible. Lots of people will try and convince you otherwise. The answer to that one is ( it is written).
There is a lot of contention about the sprinkling of the blood of Jesus. Let me be very plain about this. No person can do this, although a lot do it. Only the Holy Spirit can sprinkle our hearts clean with the blood of Jesus. I say it again no person can sprinkle the blood of Jesus. What we can do is to sprinkle our faith in this divine blood. That is different, we can have faith in a prayer like this.
