This video is well-worth your time. It records footage from a Samaritan sacrifice of a Lamb (excluding some of the most graphic parts) for the forgiveness of their sins. But the video shows how Jesus far surpasses any animal sacrifice that was ever offered and how he finally and fully offered Himself as the perfect sacrifice to atone for sins.

1 Peter 2:24 He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds you were healed.
