As John From Kentucky quoted "Don't worry about anything"
As a teacher of martial arts I have studied and thought a lot about the concept of dying and what if I'm in a situation where I just might not make it out THIS time. I wonder about why is it that I wanted to learn the things I have. Initially it was for myself but as I have gone on over the years I have found that the desire to protect those around me is far more important. So when I train, I train with that in mind, that if I were to fail while defending someone not only would it mean my defeat/death but the potential death of the person I am protecting. Martial artists don't think about things in this way nowadays, they don't look at themselves as a "warrior" would, they treat training like a game or hobby.
But I digress, the point of my explaining all of this is, to put it simply, the more I have thought about it, worrying over death is a pointless endeavor. The fact is I am going to die, so as bushido teaches, one should live their life as though they were going to die, as if today were to be your last. This way you will have no regrets. Most people do not live life this way, they think they have all the time in the world to make up their mind, achieve their dreams, etc.
Matthew 6:34 Be not therefore anxious for the morrow, for the morrow shall be anxious for its own things; sufficient for the day is the evil of it.
So all of the time I have spent contemplating and wondering about death brings me back to what the scriptures say, do not worry about it things such as this. Honor God, do your best at everything, do what you can for others, and go to the very end for whatever cause you are defending and you will live a good a life and when it is time to die, as I said, you will have no regrets.
God bless
