Grace comes when we are made to realize the futility and ephemeral nature of all things under the sun, and it is typical of human nature to resist this realization. When one thing turns to dust and ashes for us, we turn from it hopefully to something else, and so the restless search goes on. This seed of restlessness placed in the human heart is in reality a great blessing. For when we have discovered that all our fevered searching leads only to blank walls of disillusion, we begin to experience a new realization which makes way for God’s love in our heart.
