Witness Lee said this quote
“ The priesthood of Christ is “not according to the law of a fleshy commandment, but according to the power of an indestructible life” (Heb. 7:16). Aaron was constituted high priest according to the powerless letter of the law, but Christ according to the powerful element of an indestructible life. Our High Priest is constituted of a life which nothing can conquer, but which rather conquers everything! It is a life which cannot be destroyed. A life which saves to the uttermost. The endless, eternal, divine, uncreated life. The resurrection life which has passed the test of death and Hades. ”
