"Everything difficult indicates something more than our theory of life yet embraces, checks some tendency to abandon the straight path, leaving open only the way ahead. But there is a reality of being in which all things are easy and plain--oneness, that is, with the Lord of Life; to pray for this is the first thing; and to the point of this prayer every difficulty hedges and directs us." -George MacDonald
