A destination awaits all and death is the usher. One is a place of hope, love, and life everlasting. The other is one of darkness that is felt, pain which never ceases and separation from life itself.
Time always moves forward and never backwards. We come into this world, live in this world, and will eventually leave it. You cannot turn back the hand of time and live as a child again. All this to say that we are always moving in a direction towards something.
