Even after Jesus' appearance on earth, the world continues to suffer under the power of Satan and everywhere sin mercilessly persists in the bodies of men. The Apostle Paul lamented, "Wretched man that I am! Who will deliver me from this body of death ... I of myself serve the law of God with my mind, but with my flesh I serve the law of sin" (Rom. 7:24-25). As a saint, Paul was so devout and full in his love of the Lord, but his flesh continued to be oppressed by sin. This confession is not limited to Paul alone, but applies to every man alive. This is the reason why the Bible teaches us to "pray constantly" (II Thess. 5:17) to protect us from satanic invasion. Also, I John 1:10 says, "If we say we have not sinned, we make him a liar." which tells us that mankind is still under the bondage of sin. There is no one whose original sin has been liquidated.
