Humans may come up with any number of ambitious or ingenious plans or ideas, but, ultimately, forces outside of our control determine whether they fail or succeed. The sinking of the Titanic, the supposedly unsinkable ship, shows better than perhaps anything else that while man proposes, God disposes. We've given our very best to the project, and, at this point, it's up to fate whether things work out for us. Man proposes, God disposes.
