Paul gives final greetings to a number of people. Some have wondered how Paul could have known so many people in a church he never visited. No one knows for sure, but it’s possible he had met people from Rome during his travels.
Though Paul is dealing with issues of belief, he never forgot he was interacting with people, some of whom he knew and loved. For those who enjoy Bible study, there is the risk of it becoming an impersonal pursuit of knowledge. It should always include real impact on real people.
