“But when Christ came as high priest of the good things that have come to be, passing through the greater and more perfect tabernacle not made by hands, that is, not belonging to this creation, he entered once for all into the sanctuary, not with the blood of goats and calves but with his own blood, thus obtaining eternal redemption.” (Hebrews 9:11-12)
Christ, The Heavenly Priest, has actually entered the true sanctuary of Heaven that is not of human making. His place there is permanent, and his offering is his own blood that won eternal redemption. Christ spontaneously offered himself to purge humanity of sin.
“Just as it is appointed that human beings die once, and after this the judgment, so also Christ, offered once to take away the sins of many, will appear a second time, not to take away sin but to bring salvation to those who eagerly await him.” (Hebrews 9:27-28)
