In Hebrews the writer is telling us about our sanctification as it pertains to our salvation and what God did through the body of Jesus. God is communicating to us that it is His will that we have been sanctified, been made holy, and He is sanctifying us, making us holy. It has happened and is happening through the body of Jesus. This is important to understand because our sanctification or our holiness is not because of something that we do or don’t do, If we’re not careful we can treat our sanctification like a product and remove the importance of the body of Jesus.
