Hebrews 10:12-18

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]. And the Holy Spirit also adds His testimony to us [in confirmation of this]; for after having said, “THIS IS THE COVENANT THAT I WILL MAKE WITH THEM AFTER THOSE DAYS, SAYS THE LORD: I WILL IMPRINT MY LAWS UPON THEIR HEART, AND ON THEIR MIND I WILL INSCRIBE THEM [producing an inward change],” He then says, “AND THEIR SINS AND THEIR LAWLESS ACTS I WILL REMEMBER NO MORE [no longer holding their sins against them].” [Jer 31:33, 34] Now where there is [absolute] forgiveness and complete cancellation of the penalty of these things, there is no longer any offering [to be made to atone] for sin.
