In this passage, Paul finishes his letter by specifically mentioning people in the Roman church, as well as those who are with him, so that he may express his love for those whom he mentions, as well as allow those with him to express their love for the Romans.
He begins by letting the Romans know that the one who is to deliver the letter, Phoebe, is commended by him as a sister in Christ. She is a member of the church at Cenchrea, which is a place near Corinth. In verse 2, Paul explains that he is commending Phoebe so that the Romans will receive her as a saint, and that they will help her in whatever way is necessary. Then, he provides another reason to help her: because she has helped many, and helped Paul himself.
Beginning in verse 3, Paul specifically mentions specific members of the church in Rome. First, he mentions a couple that has helped him at Corinth, and who worked with him to build tents. In addition, they taught Apollos, a leader of the early church. However, in this passage, Paul says that they risked their lives for him. Furthermore, he says, every Gentile church gives thanks for them.
In verses 5-15, Paul tells the Roman Christians to let specific people know that he remembers them, and also usually provides credentials for them, to give evidence that they are in fact Christians. Then, in verse 16, he finishes his greetings by telling the Romans to greet one another with a kiss, which was a common greeting in that culture. Furthermore, he lets them know that every church greets them.
In verse 17, Paul commands the Romans to watch those who cause divisive issues, and other problems, that are contrary to apostolic teaching, and to avoid them. In the next verse, he explains that they ought to do this because such people are slaves of their evil desires, and they deceive unsuspecting people with complimentary and pleasant speech. Then, he explains that he is warning them about those people because he rejoices over them, and he wants them to be wise and innocent. He finishes this exhortation by promising them that God will soon destroy Satan, and by wishing grace upon them.
In verse 21, he begins to allow those who are with him to express their love for the Romans. First, he mentions Timothy, one of his closest disciples, and then some people who belong to his own family. Then, the one who is writing the letter for Paul greets them. Finally, some people from the Corinthian church greet them, and he again wishes grace upon them.
In verse 25, Paul begins his last words of the letter, by which he praises God. He begins by mentioning the subject of this sentence, who is God, the One who is able to maintain the Romans according to the gospel, and the preaching of Christ, which are according to the gospel, which has been kept secret, but is now revealed, and has been made known by the prophets, according to God’s command, to all people groups, leading to their obedience by faith in the gospel. Finally, he finishes the sentence by wishing all of the glory to go to God through Christ.
