Under the Law of Moses, the sacrificial system reminded devout Israelites of their sins, failures and shortcomings year after year. In this respect, it was much like a nagging mother: you know she’s right, but you wish she’d please stop talking. As the writer to the Hebrews puts it, “It is impossible for the blood for bulls and goats to take away sins.”
If that’s what Israel was looking for, it went home disappointed. The fix was only temporary.
