No I don't believe it really, and agree with PP who say it's a practical thing. If plan A collapses, unless you drop dead at that moment, your life has to take a different path, so in hindsight it seems like a door opened when in fact that door was there all along it was just a shit door you didn't want to go through because you really wanted to go through the first one.
I have had situations when I'm glad things didn't go as I initially wanted. Thank god for your unanswered prayers is another way of phrasing it. I think most people have moments like this in their lives
