He believed God is sovereign over His creation (Colossians 1:16). He believed God directs the periods and borders of nations (Acts 17:26). He believed God is in control of governmental authorities and that those that exist have been instituted by God (Romans 13:1). He believed God was sovereign over his life, knowing God had set him apart before he was even born (Galatians 1:15-16). He believed God would work all things in his life for good (Romans 8:28). So, there in prison, Paul wasn't going to lose his mind and start believing God was suddenly out of control. He didn't know how, but he knew the prison cell, the rations, and the severe conditions were under the domain of Jesus.
