God's Will?

Have you ever wonder sometimes why things are arrange to happen in such a way. It could be you had a car accident and got bang badly on the back, you may ask what if I leave home 5 minutes earlier, then you could have avoid the accident. There are so many occasions like this that we keep question and think about the what ifsss... However, whatever done is done, no matter how many times we question and think of the possibility of different ifs and the different endings, it already happened. We called it fate, we called it god's will, but back to the beginning, we actually did have the choice...
