If there really is a God….

Why does he allow us, his children, to grow old and infirm to the point where we lose our dignity as human beings; where we become like babies, dependent on others to feed us and clothe us and take us to the bathroom? Why would he want those who love us to see us diminished and humbled, a creature to be pitied? How cruel is that? Why can’t we all have our lives end on a high note?

What is the lesson that is supposed to be learned here?
