At the center of Hebrews is a long conversation about the amazing sacrifice of Jesus. In Hebrews 10 it says, “But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God. For by a single offering, he has perfected for all time those who are being made holy [Hebrews 10:12-14].” Once and for all. It is finished. By our faith in the sacrifice of Jesus, we are made clean, made perfect. No longer do we have to strive for perfection or wonder if we are perfect. We can live at peace because of the once and for all sacrifice of Jesus.
