The cause of good works, we confess, is not our free will, but the Spirit of the Lord Jesus, who dwells in our hearts by true faith, brings forth such works as God has prepared for us to walk in. For we most boldly affirm that it is blasphemy to say that Christ abides in the hearts of those in whom is no spirit of sanctification. Therefore we do not hesitate to affirm that murderers, oppressors, cruel persecutors, adulterers, filthy persons, idolaters, drunkards, thieves, and all workers of iniquity, have neither true faith nor anything of the Spirit of the Lord Jesus, so long as they obstinately continue in wickedness. For as soon as the Spirit of the Lord Jesus, whom God's chosen children receive by true faith, takes possession of the heart of any man, so soon does he regenerate and renew him, so that he begins to hate what before he loved, and to love what he hated before. Thence comes that continual battle which is between the flesh and Spirit in God's children, while the flesh and the natural man, being corrupt, lust for things pleasant and delightful to themselves, are envious in adversity and proud in prosperity, and every moment prone and ready to offend the majesty of God. But the Spirit of God, who bears witness to our spirit that we are the sons of God, makes us resist filthy pleasures and groan in God's presence for deliverance from this bondage of corruption, and finally to triumph over sin so that it does not reign in our mortal bodies. Other men do not share this conflict since they do not have God's Spirit, but they readily follow and obey sin and feel no regrets, since they act as the devil and their corrupt nature urge. But the sons of God fight against sin; sob and mourn when they find themselves tempted to do evil; and, if they fall, rise again with earnest and unfeigned repentance. They do these things, not by their own power, but by the power of the Lord Jesus, apart from whom they can do nothing.
