Welcome Paul

Romans 1:12 (NKJV) "  that is, that I may be encouraged together with you by the mutual faith both of you and me. " Why did Paul want to go to Rome?
Three things:
He Desired to Share with them
He Desired to Strengthen them
He Desired to be Strengthened by them.
When a true group of followers of Christ get together there is a lot of sharing  and caring. Each one can help each other. Paul knew that and he wanted that to happen.
