Hebrews 10:1-12 (Quoted from NLT)

1-2 “The old system under the law of Moses was only a shadow, a dim preview of the good things to come, not the good things themselves.  The sacrifices under that system were repeated again and again, year after year, but were never able to provide perfect cleansing for those who came to worship.  (2) If they could have provided perfect cleansing, the sacrifices would have stopped, for the worshippers would have been purified once for all time, and their feelings of guilt would have disappeared.

3-5 “But instead, those sacrifices actually reminded them of their sins year and after year.  (4) For it is not possible for the blood of bulls and goats to take away sins.  (5) That is why, when Christ came into the world, he said to God, ‘You did not want animal sacrifices or sin offerings.  But you have given me a body to offer.

6-7 “You were not pleased with burnt offerings or other offerings for sin.’ (7) Then I said, ‘Look, I have come to do your will, O God—as it is written about me in the Scriptures.’”

8-10 “First, Christ said, ‘You did not want animal sacrifices or sin offerings or burnt offerings or other offerings for sin, nor were you pleased with them.’  Though they were required by the law of Moses. (9) Then he said, ‘Look, I have come to do your will.’  He cancels the first covenant in order to put the second into effect. (10) For God’s will was for us to be made holy by the sacrifice of the body of Jesus, once for all time.”

11-12 “Under the old covenant, the priest stands and ministers before he altar day after day, offering the same sacrifices again and again, which can never take away sins. (12) But our High Priest offered himself to God as a single sacrifice for sins, good for all time.  Then he sat down at a place of honor at God’s right hand.”

1 Corinthians 6:11 “…But you were cleansed; you were made holy; you were made right with God by calling on the name of the Lord Jesus Christ and by the Spirit of our God.
