The blood of animals can never take away the guilt for sins.

10  Hebrews 10:1-4

10 Just like a shadow vaguely represents the thing that it is a shadow of, the laws that God gave Moses only poorly represent [MET] the good things that were to come later. Those laws were not all the good things themselves that God has promised. So, by offering the same kinds of sacrifices every year, people [PRS] who approach God can never become ◄perfect/all that God intends them to be►. 2 If God had removed the guilt for having sinned of those who brought the sacrifices, they would not feel that they were still guilty. So they would certainly have stopped offering those sacrifices! [RHQ] 3 But rather, the fact that they offer those sacrifices each year reminds them that they are still guilty for their sins. 4 The principle is that blood of animals such as bulls or goats can never remove the guilt of those who have sinned.
