Jonah had a heart problem, he didn't want to preach to people he did not like. Habakkuk had a head problem, he didn't understand what God was doing. But Daniel had a different kind of problem, he had a hostility problem, he lived out his faith in a hostile environment where people tried to use his faith in God to destroy him. In the classic story of Daniel in the Lion's Den we learn from an old man how to live out our faith in a hostile environment.
