The innocent precious blood of Jesus redeems us. There was a price against us that we could not pay, but the blood of Jesus redeemed us. 1 Peter 1:18-19 KJV says, "For as much as ye know that ye were not redeemed with corruptible things.... But with the precious blood of Christ, as of a lamb without blemish and without spot."
Jesus was holy He, therefore was worthy to have the Holy Spirit dwelling in Him and since His life was holy, His blood was holy also, making Him the perfect sacrifice for our sins. ‘For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul.’ (Leviticus 17:11 KJV).
The holy blood that was in Jesus was poured out for you and me to make atonement for our sins so that we could have a new relationship with God. God calls this new relationship “The New Covenant”. It is the blood of Jesus that seals this new covenant that God made with people. We don’t see Jesus now but one day we will. Because he is risen and alive and well, we will be too. This is the hope of every true believer in Jesus Christ and why we put our hope in Christ alone.
His blood brings us into fellowship with God. According to Ephesians 2:13 KJV, "But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ." Without the blood of Christ, man is a long way from God.
His blood cleanses. Not only does it remove the punishment of sin, it removes the pollution. I don't care what sin you've committed; "the blood of Jesus Christ His Son cleanseth us from all sin (1 John 1:7 KJV).
His blood gives power over the devil. It's the blood that Satan fears. Revelation 12:11 KJV says, "And they overcame him [Satan] by the blood of the Lamb...." The devil doesn't want you to learn about the blood. He hates it!
