Therefore, those who had been scattered went about preaching the word. Philip went down to the city of Samaria and began proclaiming Christ to them. The crowds with one accord were giving attention to what was said by Philip, as they heard and saw the signs which he was performing.Acts 8:4-8

Pray that the dispersed Christians will remain faithful in proclaiming the Gospel of Christ to the people around them.
Ask that much grace will be available for them such that the people they minister to will give attention to their message.
Pray that signs and wonders will attend their ministration.
