Christian life affect others in our society

Acts 28:11-15
Paul came to Rome, the brothers there had heard that Paul was coming, and they traveled as far as the Forum of Appius and the Three Raverns to meet Paul and his company.
At the sight of these men Paul thanked God and was encouraged.
So winter passes and the third phase of the voyage takes them safely to Puteoli, where a Christian welcome awaits.
The ship had a carved Gemini for its figurehead: "the Heavenly Twins."
In Bay of Naples they found Christian friends there and stayed with them for a week.
Why?
Luke make these record in Gentiles that shows the welcome of men and God is leading their way to Rome.
Suffering in his home town, Jerusalem and Jews, but welcomed by Gentiles. God's way is out of our expectation and mind we thought.
Jesus gave us the gospel and removed the wall in the Temple, so the activity of Christian is not limited in the Church but should go out of Church and enter the crowd to show the love of God to them.
How?
Good Christian is not in the church but live out the honor of God among our environment, the friends and unknown people. Christian life affect others in our society.
