The atonement of Christ covers sin in both forms. Under the law men could not attain to perfection in the sense of being freed from all sin. Heb. 10:1, 2; Eccl. 7:20. A remembrance of sins was made once every year. Heb. 10:3, 4. The high priest took the blood of bulls and of goats and offered it for himself and for the errors of the people. Heb. 9:7, 12, 13. "The way into the holiest of all [entire sanctification] was not yet made manifest." -Heb. 9:8. They were only sanctified "to the purifying of the flesh."-Heb. 9:13. "These all, having obtained a good report through faith, received not the promise: God having provided some better thing for us."-Heb. 11:39, 40. "For the law made nothing perfect, but the bringing in of a better hope [Christ] did."-Heb. 7:19.
A Savior was promised to the world, to deliver men from sin. Isa. 19:20. All people were commanded to look unto him and be saved. Isa. 45:22. He came. Luke 2:8-14. He is "Christ the Lord," the "Son of God." "What the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh."-Rom. 8:3. "But now once in the end of the world hath he appeared to put away sin by the sacrifice of himself."-Heb. 9:26. "He tasted death for every man."- Heb. 2:9. By the shedding of his own blood he "obtained eternal redemption for us."-Heb. 9:12. 1 Pet. 1:18, 19. Thus a fountain was opened to the house of David and to the inhabitants of Jerusalem for sin-actual transgression-and for uncleanness-inherited sin. Zech. 13:1.
