And Saul approved of his execution.
And there arose on that day a great persecution against the church in Jerusalem, and they were all scattered throughout the regions of Judea and Samaria, except the apostles. Devout men buried Stephen and made great lamentation over him. But Saul was ravaging the church, and entering house after house, he dragged off men and women and committed them to prison.
Now those who were scattered went about preaching the word. Philip went down to the city of Samaria and proclaimed to them the Christ. And the crowds with one accord paid attention to what was being said by Philip, when they heard him and saw the signs that he did. For unclean spirits, crying out with a loud voice, came out of many who had them, and many who were paralyzed or lame were healed. So there was much joy in that city. Acts 8:1-8.
Immediately after the martyrdom of Stephen, a great purge was launched against the believers in Christ. It was so aggressive that many of them fled Jerusalem. This had the unintended consequence of scattering them like seed throughout the area. And that seed started germinating new life everywhere.
It is interesting that although the apostles remained in Jerusalem, when Philip went to Samaria, the power of God went with him, even though he was not designated as an apostle. It is evidence that what Jesus commanded them was coming to pass.
“And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; they will pick up serpents with their hands; and if they drink any deadly poison, it will not hurt them; they will lay their hands on the sick, and they will recover.”
So then the Lord Jesus, after he had spoken to them, was taken up into heaven and sat down at the right hand of God. And they went out and preached everywhere, while the Lord worked with them and confirmed the message by accompanying signs. (Mark 16:17-20).
