By this will we have been sanctified through the offering
of the body of Jesus Christ once for all.
Every priest stands daily ministering and offering
time after time the same sacrifices, which can never take away sins;
but He, having offered one sacrifice for sins for all time,
sat down at the right hand of God...
For by one offering He has perfected for all time
those who are sanctified.
Hebrews 10:10-12, 14
Once for all, one sacrifice for all time, and one offering for all time. The power and the efficacy of the sacrifice of Christ on our behalf. The blood of innumerable bulls, goats, and lambs were not adequate for and were not effective in providing redemption.
The offering of the body of Christ completely sanctifies all those whom have placed their faith in Him and His work of redemption. His offering is that by which God sets us apart from sin and unto Himself. The power of that offering is in the holiness of the one who was offered up. He was the sinless Lamb of God, and in His sinlessness was the perfection and power of the offering. This one offering, thereby, which God could accept on behalf of all those who, having no intrinsic merit, would accept this specific sacrifice as their own, and therefore be sanctified wholly and completely unto God; becoming His own possession through the redemption wrought in this sacrifice
His is a one time for all time sacrifice for sins, which permanently takes away the sin of all who place their faith in Him. No sin is too strong to or too resilient to stand up to the power of His blood. He is the Lamb of God who takes away the sin of the world. In His blood was the power to cleanse the guilt of sin, and remove the guilt of sin from all who come to Him confessing their sin and need of His cleansing power; and in faith trusting in His sacrifice as the means of removal of the stain of sin upon them.
Not only has His sacrifice sanctified us and taken away the guilt of sins from us, but through that one offering we are made complete in Him for all time. Nothing else is needed, nothing else can be added, and for all time we live in the sphere of the fullness and completeness of His sacrifice. This is the Sabbath rest of God that we are to enter into. Resting in what He has brought to completion on our behalf in the once for all offering of His Son. We rest in the completeness, the effectiveness, the permanence of this one offering, by faith accepting this offering on our behalf. It is the rest of faith, resting in and resting upon this glorious truth that God in Christ has most thoroughly and completely and effectively done every thing needed to accomplish His great salvation. Which is why the author of Hebrews tells us up front to not neglect it.
Let us rejoice and celebrate this great salvation in our own hearts and souls, singing and making melody in our hearts to God. And let's share this joy and melody with those with whom we gather each Lord's day. Let our joy and thanksgiving be contagious.
Only You Father could do such a thing, could accomplish such a great salvation on behalf of those whom You have set Your great affection upon from before the foundation of the world. Who are we Lord, to be showered and lavished with such a great love? Who are we Lord? Who are we? But we are grateful, knowing our own unworthiness, but basking and glorying in what You have done on our behalf. Praise You! Glorify Your name! May Your name be great in all the earth, may it be great in our heart, and great on our lips. To You and You alone be glory, power, majesty, and dominion this day and forever! Amen.
