Christ expiated sin. He did not encourage it. He died to make your peace, and He died to make you holy, “to purify a people to Himself” (Titus 2.14). These purposes of Christ’s death cannot be separated. He is no atoner where He is not a refiner. It is as certain as any word the mouth of God hath spoken that “there is no peace to the wicked” (Isaiah 48.22). A guilty and impure conscience will keep up the amity with Satan and enmity with God. He who allows himself [to regularly commit] any sin deprives himself of the benefit of reconciliation. This reconciliation must be mutual. As God lays down His wrath against us, so we must throw down our arms against Him. As there was a double enmity – one rooted in nature, another declared by wicked works, or, rather, one enmity in its root and another in its exercise (Colossians 1.21), so there must be an alteration of state and an alteration of acts. – Stephen Charnock (1628-1680), lightly edited and clarified.
