Therefore, brethren, having boldness to enter the Holiest by the blood of Jesus, by a new and living way which He consecrated for us, through the veil, that is, His flesh, and having a High Priest over the house of God, let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water. Let us hold fast the confession of our hope without wavering, for He who promised is faithful. (Heb 10:19-23 NKJ)
The blood of bulls and goats merely atoned for the sin, a type of covering waiting for the day of redemption. We could not redeem ourselves because then it would be based on self-righteousness and good works, and because of our own sinful state, it would never be enough. As Romans tells us, ‘All have fallen short.’ Perhaps we should wait and hope that God will decide whether we are good enough, a kind of arbitrary decision, but then that would rely on gaining favor, and God would not be just.
The God who came in human flesh becomes the sacrifice that meets the full requirements of the law. Having that full assurance, let us hold fast to the confession of our hope, don’t waver, God is faithful.
