Hebrews 9:11-12

11But when Christ appeared as a High Priest of the good things to come [that is, true spiritual worship], He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not a part of this [material] creation.

12He went once for all into the Holy Place [the Holy of Holies of heaven, into the presence of God], and not through the blood of goats and calves, but through His own blood, having obtained and secured eternal redemption [that is, the salvation of all who personally believe in Him as Savior].
