Time passes without stopping and, my body, even during my lifetime, constantly changes and passes on, and the whole world as is seen in its motion, also passes on, as though it were hurrying to its appointed end, like a machine in motion. Where, then is constancy? Constancy is that which moves and directs all this to its purpose. God, the first Cause of all that is complex and created is constant, being Himself not complex, and therefore not passing but eternal. The souls of angels and men, created after the image of the first Cause, are also constant.
Everything else is like a soap bubble.
~St John of Kronstadt
