Hebrews 10:1

Hebrews 10:1 says, For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.  The law of God, given to Moses, was but a shadow of salvation through Christ.  The law of God could never save anyone's unless they fulfilled all aspects of the law.  If people could be saved by the law, then there would be no need of a daily and yearly sacrifice, but this was never the case.  

Verse two adds, For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.  This is a further pointing out of the temporary nature of man-made sacrifices.  They were done by the instruction of God, but they were never capable of bringing salvation.  If they could, then once they purged the sins of the people, they would no longer be necessary.  

Verse three continues, But in those sacrifices there is a remembrance again made of sins every year.  The sacrifices made under the law of God were but a reminder that people were still under the power of sin and death.  These sacrifices were but a temporary reprieve and not an everlasting pardon.  

Verse four declares, For it is not possible that the blood of bulls and of goats should take away sins.  The bulls and goats had no say in the matter of the sacrifice, nor were they equal to people.  Just as the blood of the bull and goat could not bring everlasting salvation, neither can the blood of anyone except Christ.  We cannot die to bring forgiveness to others or even to ourselves.  

Verse five adds, Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:  Christ came to offer His body as a sacrifice for our sins.  

Verse six continues, In burnt offerings and sacrifices for sin thou hast had no pleasure.  Burnt offerings and sacrifices were never intended to bring everlasting forgiveness.  They were to show the willingness of God's people to acknowledge their sins and ask His forgiveness.  Even this had become perverted as the religious leaders used these rituals to profit for themselves and to control others.  Salvation through Christ can never be controlled by anyone nor any group of people.  If any church claims to control the salvation of its members, then it is not being true to what God's word teaches.
