Hebrews 10:11-13

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]
