Hebrews 10:9-14

then He said, “BEHOLD, I HAVE COME TO DO YOUR WILL.” [And so] He does away with the first [covenant as a means of atoning for sin based on animal sacrifices] so that He may inaugurate and establish the second [covenant by means of obedience]. [Ps 40:6-8] And in accordance with this will [of God] we [who believe in the message of salvation] have been sanctified [that is, set apart as holy for God and His purposes] through the offering of the body of Jesus Christ (the Messiah, the Anointed) once for all. Every priest stands [at his altar of service] ministering daily, offering the same sacrifices over and over, which are never able to strip away sins [that envelop and cover us]; whereas Christ, having offered the one sacrifice [the all-sufficient sacrifice of Himself] for sins for all time, SAT DOWN [signifying the completion of atonement for sin] AT THE RIGHT HAND OF GOD [the position of honor], waiting from that time onward UNTIL HIS ENEMIES ARE MADE A FOOTSTOOL FOR HIS FEET. [Ps 110:1] For by the one offering He has perfected forever and completely cleansed those who are being sanctified [bringing each believer to spiritual completion and maturity].
