Ro 6:10  For in that he died, he died unto sin once: but in that he liveth, he liveth unto God. 

He 9:28  So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation. 

He 10:10-14  By the which will we are sanctified through the offering of the body of Jesus Christ once for all

11  And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: 

12  But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; 

13  From henceforth expecting till his enemies be made his footstool. 

14  For by one offering he hath perfected for ever them that are sanctified.
