And without the shedding of blood there is no remission. Heb:9:22 Bloodshed is needed for forgiveness, shows that sin is serious. For He is a holy God. And sinful and wretched people like us, fallen and marred can have access to holiness, only by the shedding of innocent blood. In the garden of Eden, God showed the example. The Hebrews were asked to do it. And the culmination of the shadow of the things happening in the Old Testament, happened on the cross, once and for all. That is why He said, it is finished. So let us approach the throne of grace with boldness. Image credit: https://www.christianity.com/wiki/bible/why-hebrews-922-say-without-the-shedding-of-blood-there-is-no-forgiveness.html
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!
