Acts 13

I feel as though an alternate title for Acts could easily "God takes bad things that happens to Christians and works them out for good" Acts 13 has an excellent example of this in verses 46-48:

And Paul and Barnabas spoke out boldly, saying, “It was necessary that the word of God be spoken first to you. Since you thrust it aside and judge yourselves unworthy of eternal life, behold, we are turning to the Gentiles. 47 For so the Lord has commanded us, saying,

“‘I have made you a light for the Gentiles,
that you may bring salvation to the ends of the earth.’”

48 And when the Gentiles heard this, they began rejoicing and glorifying the word of the Lord, and as many as were appointed to eternal life believed.

If you read Paul's letters, it's impossible not to notice that his heart's desire was to see his fellow Jews become follows of Christ. And yet, at every turn he finds this wish thwarted. I can imagine it would be easy for Paul to be disappointed and complain "Why won't God let me reach these people?".

But instead of losing hope, Paul preaches to the gentiles without a lack of enthusiasm, sowing the seeds of the Christian church throughout the Roman empire. How much less would Paul have accomplished if he had been able to remain in Judea preaching only to Jews the whole time. Instead, because of Paul's willingness, God was able to take a bad circumstance and turn it into an even greater good.
