Just Once. - Hebrew9:12

In the old, the priest has to offer sacrifices of blood for himself and others for their cleansing. No one is better, not the priest nor the followers.

So there can’t be a perfect cleansing which results into renewal often. When God used man, now God used Himself, He decided not to send man to that holy of holies, holiest place with goat’s blood again but to go Himself with His own blood and recover man from the loss.

Now He did it once and final, He gave that blood once to last till eternity, we are cleansed each moment we believe.

 Hey! You don’t have to consult a priest anymore, now you can go straight to the High Priest in prayers. How beautiful! In case you are waiting for Him to repeat the process before you believe, then you are on your own, because He did it once, and just once!
