As a pluralist, I had a lot of questions about prophet Muhammad before recognizing him as a peace maker and a mercy to mankind. I have been skeptical about the divine status accorded to religious masters in every tradition including Islam.
You can make your life purposeful, meaningful and enjoyable, and can choose to be the driver of your life or be driven by others. The choice, as well as the excuse, is yours. I pray that we retain the ability to choose what we want in our lives.
