Contexte: My soul has grown over the years, and some of my views have changed. As long as I am alive, I will continue to try to understand more because the work of the heart is never done. All through my life I have been tested. My will has been tested, my courage has been tested, my strength has been tested. Now my patience and endurance are being tested. Every step of the way I believe that God has been with me. And, more than ever, I know that he is with me now. I have learned to live my life one step, one breath, and one moment at a time, but it was a long road. I set out on a journey of love, seeking truth, peace and understanding. l am still learning.
