There are spiritual laws here... even God goes by them, because he wants a certain type of creation... free will sovereign spirit beings...

even Christ could not perform miracles in town where the people were very opposed to Him... at least He would not do so, it seems, because it would infract upon the free will of the people there...

once He died and was resurrected, He says He was given the power on earth and in heaven...

there are reasons for blood sacrifices... why do you think occult practice it...

it is likely energetic and following rules of creation God set up...
