God's plan must be executed successfully

Acts 23:25-35
The Centurions wrote a letter to the governor Felix, "..I found that he was being accuse about questions of their law, but charged with  nothing deserving death or imprisonment..."
Felix asked Paul what province he was from.
Why?
The Centurions knew that Paul is should be freed, for Paul did nothing deserving death or imprisonment. But Felix did not really want to judge this affair but wanted to get some profit from Paul. So Paul was under worse situation. But God has his plan and always protects Paul's safety.
How?
Even the situation is worse but the salvation program is keep going. God is the Sovereign Lord!God's plan must be executed successfully.
