Animal sacrifices are no longer needed because Jesus Christ’s sacrifice was once for all – unlike animal sacrifices which had to be offered “Continually, year by year”. Heb 10:10 says by which will we are sanctified through the offering of the body of Jesus Christ once for all.
Don’t forget there are two sides to a coin. But if Jesus is truly the way, the truth and life, then your decision will determine where you will spend eternity – either in heaven or hell.
