And Saul approved of their killing him. On that day a great persecution broke out against the church in Jerusalem, and all except the apostles were scattered throughout Judea and Samaria.
Acts 8:1 NIV

I wonder about this. Did the apostles send everyone else away to keep them safe and they stayed together but lived in fear. Or did the others run away and the apostles stay because they were not afraid. At a youth group event last night the speaker talked about fear and used Matthew 14 where Peter gets out of the boat. He pointed out that Peter was bult different and so should we be. And when you are built different you believe different (who Jesus is and who you are. what God can do and what you can do). When you believe differently you behave differently. (you do things you would not do without faith) And when you behave differently you Battle differently. (battle with your faith and focus and it only takes a tiny amount of faith to move mountains)

You don’t have to put your faith in your ability to do something for God you just have to believe in God.

Those who had been scattered preached the word wherever they went.
Acts 8:4 NIV

Even those who scattered were able to do things for God that those without faith would not do.

Now an angel of the Lord said to Philip, “Go south to the road—the desert road—that goes down from Jerusalem to Gaza.”
Acts 8:26 NIV

Here is another example of God telling someone to go. With very little detail. Why do they go? They are built differently because of their faith.

Then Philip began with that very passage of Scripture and told him the good news about Jesus.
Acts 8:35 NIV

All that he has to do is show up and God has everything in place so all he needs to do is show up and respond to what God is already doing. The Ethiopian was already reading exactly what he needed to be reading and the Holy Spirit gave Philip just what he needed to say.
