Jesus is offered once to bear the sins of many, and He appears a second time to bring salvation to those who wait for Him. The second time He comes, He comes “not to bear sin” as He does the first time. The second time He comes, He comes with salvation completed.
Jesus suffers only once, not many times. Rather, He removes “sin by the sacrifice of Himself” and this only once. (Hebrews 9: 25, 26) This is in sharp contrast to the high priest who must enter the sanctuary “yearly with the blood of another.” (Hebrews 9: 25) Jesus offers His own blood, and He offers it only once.
The law is “only a shadow of the good things to come” and “can never perfect the worshipers by the same sacrifices they continually offer year after year.” (Hebrews 10: 1) Jesus comes to fulfill the demands of the law, and He does this only once. With Jesus’ death and shed blood, He satisfies the law’s demands. God the Father is satisfied with Jesus’ sacrifice.
“Now where there is forgiveness of [sins and lawless acts], there is no longer an offering for sin.” (Hebrews 10: 17, 18)
