We can at least see those events as turn signals for us. We are not immune. We never know what tragedy may befall us because of someone else, by chance accident, or even through our own foolish mistakes. Therefore, we should always be ready - make the most of each moment we're given, major on the majors and not the small stuff, and keep all our relationships in good order, especially our relationship with God. This has been the underlying reality at every funeral I've ever attended.
Life is short and fragile.
Therefore, we should pay attention to our lives, forgive more easily, tell people we love them more often, and stay close to God. Don't tell yourself there will be time later to straighten out your affairs. Don't assume you can get around to your family later when there is more time. Don't think after you do some other things you want to do first, you will make your peace with God later. Later may not belong to you.
