As I read through the Bible it seems to me that regardless of what is happening, God seems to be in control. For instance, look at Acts 2:9 – 11. There were people from many nations in Jerusalem to celebrate Pentecost. They were Jewish believers. How did they become Jews? Born that way or converted. Many were in all likelihood converted.
Isaiah 49:6 is a bit like the Old Testament great commission. It was God’s intention for Israel to be a light to the nations. He chose them to represent Him to the world. They did not do that well. So in 722 He had Assyria take Israel into captivity. 136 years later Babylon took Judah into captivity. Israel and Judah were settled in some of the nations that are represented in Acts 2:9 – 11. Like Daniel did with Babylon some of these people were continually faithful to what God had revealed of Himself. As Daniel had an impact on those he met, so would have they. Some would have converted to the worship of the Hebrew God.
The Audience Primed
Those people’s descendants could have been those from the nations listed in Acts 2:9 – 11. God used the captivities to spread knowledge of Himself to the nations to which the Jews were displaced.
In Acts 8:1 we read that a great persecution arose after the stoning of Stephen. Some in the Church scattered. They carried the message of Christ to the places they went.
The Gospel Spread
As with the captivities God used the persecution to spread the good news of the gospel.
It seems He moves us where He wants.
