Mutually encouraged by each other's faith

Romans 1:8-17
Paul trusted that the way to Roman will be opened for him by the Lord.
Paul wanted to impart some spiritual gift to make them strong.
Strong - mutually encouraged by each other's faith.
Gospel is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
For in the gospel a righteousness from God is revealed, a righteousness that is by faith from first to last. The righteous will live by faith.
Full of warm, human feeling. Paul greatly appreciates this group of Christians he has never met.
He longs to see them and share with them all that the gospel means.
Greek and non-Greek; those who were not Greek were considered uncivilized.
