Hebrews 9:24-28

For Christ hasn't entered a Most Holy Place constructed by human beings that is only a pattern of the original. He has entered heaven itself, and now appears on our behalf, speaking for us in God's presence. This was not to repeatedly offer himself, like a high priest has to enter the Most Holy Place year after year, offering blood that is not his own. Otherwise Christ would have had to suffer many times since the creation of the world. No: just this one time at the end of the present age he came to remove sin by sacrificing himself. Just as human beings die only once, and then are judged, so too for Christ—having been sacrificed once to take away the sins of many people, he will come again, not to deal with sin, but to save those who wait for him.
