Before digital photography was so common, photographers often developed film by immersing images in various solutions. When pictures were placed in the developing fluid, they would change. Once the picture was put in the "stop bath," the image became fixed and could n longer change.
Our lives on earth are like the pictures in the developing fluid. We can change and alter them. Our deaths are like the "stop bath," forever freezing our life as it is at that moment in time.
God is the photographer who is controlling this process. He decides how long we need to develop before He stops our life. While I am still alive, God is still shaping me. I am not a finished product yet. I need to be willing to be molded.
