22 News of this reached the church in Jerusalem, and they sent Barnabas to Antioch. 23 When he arrived and saw what the grace of God had done, he was glad and encouraged them all to remain true to the Lord with all their hearts. 24 He was a good man, full of the Holy Spirit and faith, and a great number of people were brought to the Lord.25 Then Barnabas went to Tarsus to look for Saul, 26 and when he found him, he brought him to Antioch. So for a whole year Barnabas and Saul met with the church and taught great numbers of people. The disciples were called Christians first at Antioch.
We have to face such numerous and strong enemies all the time, and our minds are so slippery, that it will be lost straightaway unless each one arms himself diligently. We have countless instances of such falling away. Luke describes how to persevere: we are all to remain true to the Lord with all our hearts. This teaches us that faith has taken deep root when it has a place in the heart.
Faith is not something separate from the Holy Spirit but is mentioned as a particular sign of Barnabas’ being full of the Holy Spirit.
