Heb:9:12 Not with the blood of goats and calves, but with His own blood He entered the Most Holy place once and for all, having obtained eternal redemption. The second part behind the veil, The Holy of Holies - the high priest entered once a year after purifying Himself and offering sacrifice for all. But now... The veil has been torn. In the New Covenant, Jesus Christ, the great High Priest entered the Holy of Holies with His own blameless blemishless blood, once and for all. It is finished. No more barrier. No more inaccessibility because of sin. Everything has been dealt with, so wonderfully and perfectly that we can have access to the Holy God, through the blood of the Son. Hallelujah!
For I will be merciful to their unrighteousness and their sons and their lawless deeds I will remember no more. Heb:8:12 The New covenant has been established. The old covenant is obsolete now. Mercy has been given to undeserved rebellious people like the bard. The old covenant, the law demanded justice. The New covenant also demands, but He Himself met with justice out of love. God hasn't changed a bit. But He has bore it upon Himself, covered justice with love. Holiness of God mingled with love on the cross. What amazing climax. Filled with hope for the hopeless person like me.
