OK, so Paul is introducing himself to the church in Rome and he needs to gain their trust and respect.
How does he do it?
“For I long to visit you so I can bring you some spiritual gift that will help you grow strong in the Lord. When we get together, I want to encourage you in your faith, but I also want to be encouraged by yours.”
So, bringing a gift, that should help. But more importantly a spiritual gift, something expressly given him by God to give away to the churches for their spiritual gain.
Then, he further expresses what will happen when they meet. Encouragement between them – Paul to the church in Roma Rome (tip of the hat to my ancestors!) and the church in Rome to Paul.
Now, how does that happen? What does it look like?
Paul knew that Christian ministry flows two directions. The church, after all, is a body. All the parts serve, nourish and enhance one another.
He shares and encourages others and the church shares and encourages him.
