Death often happens suddenly. A car accident, a plane crash, a fatal fight, a war, a flood, and so on. When we feel healthy and full of energy, we do not think much about our deaths. Still, death might come very unexpectedly.
How can we be prepared to die? By not having any unfinished relational business. The question is: Have I forgiven those who have hurt me and asked forgiveness from those I have hurt? When I feel at peace with all the people I live with, my death might cause great grief, but it will not cause guilt or anger.
When we are ready to die at any moment, we also are ready to live at any moment.
