In these final verses of Chapter 1, Paul shows us that no matter who we are or what we have accomplished, we all have corrupt desires as a result of our rejecting God as Lord of our lives. While the corrupt desires vary from person to person, the solution for forgiveness is the same for all of us: surrendering to Jesus as Lord and Savior.
