"And when an attempt was made by both the Gentiles and the Jews with their rulers, to mistreat and to stone them, they became aware of it and fled to the cities of Lycaonia, Lystra and Derbe, and the surrounding region; and there they continued to preach the gospel.  And at Lystra there was sitting a certain man, without strength in his feet, lame from his mother's womb, who had never walked.  This man was listening to Paul as he spoke, who, when he had fixed his gaze upon him, and had seen that he had faith to be made well, said with a loud voice, 'Stand upright on your feet.'  And he leaped up and began to walk."

This is often the way God works in our lives; in the way that we least expect.

When Paul and Barnabas are threatened with death, they do not consider that reason to stop preaching, but to preach all the more.  So they go to other regions. 

Once there, God moves mightily in their lives.  God also moves in the lives of the people that are listening.

This is basic church growth.

"Go ye into all the world" means "go" to Paul and Barnabas.

It is not a cowardly thing to stop preaching when you are threatened.  But it IS a Godly thing to keep on preaching.

Be bold - keep on preaching.
