All good things past, present, and to come, were and are founded upon the priestly office of Christ, and come to us from thence. Our High Priest entered into heaven once for all, and has obtained eternal redemption.
The Holy Ghost further signified and showed that the Old Testament sacrifices only freed the outward man from ceremonial uncleanness, and fitted him for some outward privileges. What gave such power to the blood of Christ?
It was Christ's offering himself without any sinful stain in his nature or life. This cleanses the most guilty conscience from dead, or deadly, works to serve the living God; from sinful works, such as pollute the soul, as dead bodies did the persons of the Jews who touched them; while the grace that seals pardon, new-creates the polluted soul.
Nothing more destroys the faith of the gospel, than by any means to weaken the direct power of the blood of Christ. The depth of the mystery of the sacrifice of Christ, we cannot dive into, the height we cannot comprehend.
We cannot search out the greatness of it, or the wisdom, the love, the grace that is in it. But in considering the sacrifice of Christ, faith finds life, food, and refreshment.
