After the Jewish people killed Jesus and Stephen, the Lord God chose Paul to minister to the Gentiles.
For another example of this, please read more about this in the following verses.
42 As Paul and Barnabas were leaving the synagogue, the people invited them to speak further about these things on the next Sabbath.
43 When the congregation was dismissed, many of the Jews and devout converts to Judaism followed Paul and Barnabas, who talked with them and urged them to continue in the grace of God.
44 On the next Sabbath, almost the whole city gathered to hear the word of the Lord.
45 When the Jews saw the crowds, they were filled with jealousy and talked abusively against what Paul was saying.
46 Then Paul and Barnabas answered them boldly: “We had to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we now turn to the Gentiles.
47 For this is what the Lord has commanded us:
“‘I have made you a light for the Gentiles,
that you may bring salvation to the ends of the earth.'”
48 When the Gentiles heard this, they were glad and honored the word of the Lord; and all who were appointed for eternal life believed.
Consider me a happy Gentile believer.
I am amazed that the Lord God has accepted this sinner as a believer, that He sanctifies me.
He covers me with His righteousness.
You Oh Lord are so worthy of our praise.
May You continue to be with me, changing me more into the man You want me to be.
