In Hebrews 10:1-18, the sacrifice Jesus made on the cross was the final sacrifice for us - the once and for all - ultimate sacrifice. We are cleansed completely from any and all sins if we believe in Jesus. If we believe and have faith in Jesus, God "will never again remember our sins and lawless deeds." We are made holy because of the sacrifice Jesus made for us on the cross when He suffered, died, and rose from the grave. We are forever made holy because of Jesus. Jesus offered Himself to God as a single sacrifice for sins, good for all time - for all eternity.
