"Therefore they that were scattered abroad went every where preaching the word." Acts 8:4 KJB
Under great persecution the people scattered but they also spread the gospel as they went. They were able to speak to people that they would not have had the opportunity to speak with had they not been on the run.
God will have his word going out to people. In this case, I see God had chose to put a little fire under their feet to get the job done in more areas.
