Heb 10:11-14

11 Every priest goes to work at the altar each day, offers the same old sacrifices year in, year out, and never makes a dent in the sin problem. 12 As a priest, Christ made a single sacrifice for sins, and that was it! Then he sat down right beside God 13 and waited for his enemies to cave in. 14 It was a perfect sacrifice by a perfect person to perfect some very imperfect people.
