When we realize what Christ has done on our behalf, we want to do the things that please Him. If we love Him, the Bible says, we will keep His commandments. In other words, a person will not continue in an adulterous relationship.
Have you read Romans chapter 7 recently?
While I agree that the Spirit enables us to obey the commandments, temptation remains and obedience is not automatic. Even those who love God sometimes falter.
