Our life is not in our hands. God owns our life and He determines how long we can live. This is one of the great lessons which we can learn from death. The knowledge of death makes us know that there is God who controls everything. Only this God cannot die. Every other thing which he created are liable to die.
When we remember that death is coming, then we know that there is an inevitable appointment which every human being must keep. The appointment with death is an appointment which is appointed unto every man. No matter how many years we live here on earth, one day we shall die. No matter how rich or famous we might be, one day death shall come.
It is wisdom, if we consider that after death judgement shall come. We must learn to apply our hearts to wisdom. We must learn to do what is right and avoid what is evil. We must show goodness and love among men. We should show them the way of life. Let us live everyday with the mindset that the day of judgement is coming.
