God is in control. We can trust Him and seek Him and participate with Him in the work even when things are difficult. 

The big challenge of this text is that Paul had a clear understanding of his call and what his next steps of obedience were to be while still in Ephesus. (19:21) He was to go to Jerusalem and then go to Rome yet here he is in a prison in Caesarea - and the text tells us he’s trapped here for TWO years. Talk about God changing his plans. Yet, in this tragic situation, Paul gets the unique chance to preach the gospel to Felix and his wife for literal years, not his plan, but obviously God’s plan and Paul rolls with it.
