Paul explains that the way sin was taken away from the people in the Old Testament; through the shedding of the blood of animals can no longer take away the sin. Instead we “…are sanctified through the offering of the body of Jesus Christ once for all.” (Hebrews 10:10) The sacrifice, also known as the Atonement of Jesus Christ was the ultimate price paid for the sin of mankind. Jesus Christ gave us a way to return to live with our Heavenly Father again.
Paul invites those followers of Christ to “…draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.” (Hebrews 10:22) For if we sin after we come to the knowledge of Him, it will be difficult for us to be forgiven, for we know right from wrong;
“For if we sin willfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins.” (Hebrews 10:26)
Essentially Paul is telling us that we need to live by faith and once we have knowledge of our Redeemer, we need to live a pure and clean life (as best our abilities).
