Are you willing to make a sacrifice when you do something wrong intentionally or unintentionally? Would you sacrifice your wealth or success for a greater good at a certain time? When the Tabernacle and Temple my ancestors did just that as they brought their most worthy possessions (their animals) to the mount to be sacrificed to G-D. Yet this sacrifice was only for mistakes they made to G-D for sins that were committed against fellow human beings forgiveness from those individuals must also be sought. Today we don’t have the Temple to offer such a sacrifice but if instead when we sinned ( intentionally or unintentionally) we truly asked to be forgiven and gave of our financially reasons and/or other means to those less fortunate I believe that sacrifice would cleanse our souls as well.
