There is the famous story of the great English biologist Alfred Russell Wallace. Now this story has many variants, as you may know. But variously put, they are all pointing out a valid, universal truth. In this particular version of the story he was observing an Emperor butterfly emerging from its chrysalis. It was moving about inside its prison, struggling with all its feeble might to get free, but seemingly it wasn't going to make it out unaided. Pitying the struggling creature and thinking to help the process along, he slit the chrysalis open with his knife. Did a beautiful new butterfly flit out and spread its wings in the glorious sunshine? No! On the contrary, what happened was horrible to behold. The butterfly emerged but grew ever weaker and perished right before his eyes! Wallace concluded that the butterfly's painful struggle out of the prison-house of the chrysalis was essential to give it the vital strength it needed to survive. So too with human beings (and to my own life experience starting when I was five years old, suddenly pulled out of Kindergarten class and told by my mother in the family car that my dad had crashed in his plane and died!). The darkness and the painful struggle that disasters bring to us are sometimes absolutely necessary to bring forth new life and a meaning to complex tangles of events and circumstances.
A very great statesman of Britain knew this fact of life. He said, "Out of intense complexities intense simplicities emerge." That man was Winston Churchill, who rallied his British people and nation to stand up alone against the seemingly unconquerable might of Hitler and Nazi Germany.
