I'll take that as your refusal or inability to respond to the post!
Get a grip. Christ died for all sins of all men. He was the Sacrifice for us to erase our sins before God. However, we must accept that sacrifice, and adopt the necessary attitude towards it--else it does no good whatsoever.
The OT concept of sacrifice was to kill an animal and offer it to God--symbolizing the killing of our sins toward Him. The reason people sacrificed their bast animals (or should have) was to show God that we were giving our best towards Him. However, killing animals was never a good enough sacrifice for all our sins--it just pushed them back a little.
Christ changed that. He became our sacrifice for all time. A perfect, blameless sacrifice that would mean we never have to perform sacrifices of animals to God again. However, without belief, without the acceptance of what that sacrifice means, it does nothing. It would be just as if the shepard killed a lamb out of hunger, rather than on an altar. Then same thing is accomplished (killing of the lamb), but the results are vastly different--because of the attitude of the shepard.
That is the meaning of sacrifice, and why we must take the attitude of acceptance towards His sacrifice--otherwise a lamb is just killed, with no meaning behind it.
