10 God's laws which he gave to Moses are like a shadow of the good things that would come later. But those laws do not show exactly what those good things are like. They say that the priests must continue to offer the same sacrifices on behalf of the people, year after year. So those sacrifices can never make the people completely clean when they come to worship God. ² If the old rules could do that, the priests would have stopped offering sacrifices. The people who came to worship God would have become completely clean once, for all time. They would no longer have trouble in their minds about their sins. ³ But as it is, those sacrifices every year cause people to remember their sins.
