Really, Paul just wants all the Romans to live in harmony together and glorify God together without worrying about their differences.
Remember, Christ is with the Jewish-Christians and the Gentile-Christians, too. So let's all play nice.
Paul actually has a good feeling about the Romans. He knows they're upstanding people who are knowledgeable and can help each other do what's right by God.
He's only written to them to tell them all this and to give them advice because of his special relationship with God. What can we say?
The Big Guy loves helping Paul write all his correspondence. Not that's he's bragging or anything.
Paul would only ever brag about all the good things that God has done through him. So modest.
For example, Paul has won tons of converts through the entire Roman Empire, but that's all God's doing. He made that happen.
Paul's not usually in the business of preaching about Jesus where people already know him. He also doesn't usually come into a church community he didn't found, like the one in Rome, and start handing out advice. No, never…
That's why he hasn't been to see the Roman Christians in person yet. He's been meaning to, but there are just so many non-believers who need to hear the good news first hand. Paul's got a busy schedule.
But now he's fresh out of non-believers to convert in the area, so he's going to head over to Rome soon and stay a while on his way to preach the gospel in Spain. Oh, bull fighting? Not, quite.
Before that, Paul has got to make a quick pit stop in Jerusalem. The folks in Macedonia and Achaia have taken up a nice collection for the poor there and he's gonna drop off the money.
Paul tells us that these Gentile-Christians are more than happy to share their material blessings with the Jewish-Christians in Jerusalem because they're getting a pretty big share of the spiritual blessings from Christ. Fair is fair.
Paul's also hoping that the Romans might pray for him so that he doesn't get taken down by the non-believers in Judea (like Jesus before him) and that he does a good job for all the Christians there. Amen, brother.
