In old testament times a Jewish man would take animal the best of what he had and it would be slain and the blood from that animal would be put on the altar. This would be the offering for the whole family.
In this new testament times we offer ourselves to God at the moment of our salvation. At baptism we rise out of the water likening ourselves to the resurrection of our Lord Jesus.
There it then a cleansing process that the word of God and the ministry of the Holy spirit leads us into. Is it not wonderful that the Holy Spirit ministers to us bringing the word and the purpose of God into our lives. In 1 John Verse 7. It says
But if we walk in the light as he is in the light. We have fellowship with one another and the blood of Jesus Christ his Son cleanses us from all sin.
The Holy Spirit and the blood of Jesus are a ministry to us that work together. Did you see what that verse says. Cleansed from all sin, now that really is something. So what about this wonderful and divine ministry that comes from the throne of Grace. As they minister to us ( Yes that is you and me ) the Holy Spirit teaches us about the fullness of the blood of Jesus. When we grasp this glorious truth and apply it to our lives. We are moving into a spiritual realm we have not been in before
Job Chapter 27 verse 6. My righteousness i hold fast and i will not let it go. My heart will not reproach me as long as i live. This talks about our conscience as being heart felt. So the Holy Spirit talks to us and our minds are renewed and the next thing? Our hearts of course sprinkled with the blood of Jesus. Washed clean in the blood of the lamb. That is the care and love that our God has for us. So that when we present ourselves to him we are Holy as he is Holy. Now this takes some working on. The best bit? we have the greatest teacher in the whole of the universe and the blood of Jesus which is as fresh and as warm as the day he shed it and will be forever! oh Glory to the Lamb what a God we serve and he sends his Spirit to us. Now i do not know about you but i say it does not come any better than that. Amen.
