There is no remission of sin without the shedding of blood. Since Jesus was the perfect sacrifice, it is no longer necessary to offer sacrifices of blood for forgiveness of sin. Jesus fulfilled the old covenant law completely and established a new covenant for us. In the Old Testament, no one could go into the Holy of Holies except the chief priest and he could only go once a year. Now, because of the new Covenant, we can enter into God”s throne room at anytime. Our bodies have been washed and we are cleansed by His blood.
7 But if we live in the light in the same way that God is in the light, we have a relationship with each other. And the blood of his Son Jesus cleanses us from every sin.–1 John 1:7 (GW)
The blood of Jesus cleansed sin yesterday, it cleanses sin today, and it will cleanse sin tomorrow. We can hold on to our declaration because the One Who paid the price and established the New Covenant is faithful. Even in times of persecution, we can know that He will never let us go.
12 For this reason I also suffer these things; nevertheless I am not ashamed, for I know whom I have believed and am persuaded that He is able to keep what I have committed to Him until that Day–1 Timothy 1:12 (NKJV)
