“Force of God” and “law of attraction” is something that are unknown events — events if known, you would have stopped it from happening or have identified an alternative.
My question is do you have risk management in place. Have you documented the uncertain events that may happen – process, people, technology, etc – thought about how to respond to them. If you priortize them based on the severity and engage the customer in this process – it is sure the customer will appreciate the effort, rather than seeing it as surprise later.
