For it is impossible for the blood of bulls and goats to take away sins.
Hebrews 10:4

It was impossible for the blood of animals to take away sins outside the gates of Eden, in the Wilderness, at the Tabernacle, or at the Temple. Sin and guilt offerings were always temporary measures to allow us to be in God's presence in spite of our constant failures.

#yeshua's blood removes our sin completely, replacing our sinfulness with his absolute righteousness, allowing us not only to enter God's presence, but to live in it for eternity.
