Years ago, I heard someone say, "Those bloody Baptists."  Which was meant to be derogatory.  But Methodists, Church of God, Pentecostals, and most other main stream churches are on the same page as the Baptists.  You can't have salvation without sacrifice.   The Jews sacrificed a perfect lamb for their sin.  They had to do this every year.   (We call Jesus "The Lamb of God.")

Peter put it this way:  Peter 1: 18a-19, 21  "For you know that you were not redeemed with corruptible things, (such) as silver and gold…But with the precious blood of Christ, as of a lamb without blemish and without spot...Who by him (we) do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God."

They used to tie a rope around the Jewish priest that (once a year) took the blood of an unblemished lamb into the holy of holies.  If the priest touched the Ark of the Covenant he would die.  Then they needed a way to get him out--since they couldn't go in--so they pulled on the rope.  Sacrifice for sin was done with blood.  But they were saved just as we are.  By faith.  Faith in a coming sacrifice that would take away sin once and for all.

An interesting moment occurred when Jesus died.  Mark 15: 37-38 "And Jesus cried with a loud voice, and gave up the ghost.  And the veil of the temple was rent in two from the top to the bottom."  This was the veil that separated the holy of holies from the rest of the Temple where that one person, once a year went in.  But when Jesus died, this huge veil, many, many feet high began to rip from the top down.  In an instant, the veil was torn open, and the holy of holies was revealed.  Torn open in the instant that Jesus gave up his spirit and died.

With Christ's death, his blood was given to seal our salvation.  And with the veil ripped open, God was saying, "Welcome.  Come on in.  Welcome to this holy place.  Talk to me.  You don't need a priest anymore, your sins are forgiven.  Covered by the blood of my son, Jesus."
