Full of the Holy Spirit and faith

Acts 11:19-30
Barnabas was a good man, full of the Holy Spirit and faith, and a great number were brought to the Lord.
Then Barnabas went to Tarsus to look for Saul. So for a whole year Barnabas and Saul met with the church and taught great number of people. The disciples were called Christians first at Antioch.
At about the same time as the events in Caesarea, thing are moving in the north, at Antioch, third largest city in the world (after Rome and Alexandria), busy commercial center and capital of the Roman province of Syria.
The warm response of the Greeks to the Christian message leads the Jerusalem church to dispatch Barnabas to Antioch. He in turn tracks Saul down at his home city of Tarsus. And the stage is set for the next great advance, described from chapter 13 onward.
Lord: A more suitable title for Jesus in the Roman world than the Jewish 'Messiah'. As the Romans declared 'Caesar is Lord' so the Christians declared 'Jesus is Lord'.
A severe famine:  in the days of Claudius: Claudius was emperor AD 41-54, The famine hit Palestine about AD 46.
Why?
Barnabas was dispatched to Antioch, he needs someone to help him to teach people, so he went to invite Saul to work with him. He had the vision that God will use Saul.
To improve the work of the Lord, we should find proper coworker and work together.
God wants us build church with others, no one can build church by himself, find a team with faith and Holy Spirit to build church.
Full of Holy Spirit and faith is the requirement to be a good servant of the Lord.
How?
May I could be full of the Holy Spirit and faith to be a good coworker to build other's life.
