I have seen almost all the beautiful things that God has made; I have enjoyed almost every pleasure that he has planned for us; and yet as I look back I see standing out above all the life that has gone four or five short experiences when the love of God reflected itself in some poor imitations, some small act of love of mine. And these seem to be the things which alone of all one’s life abide. Everything else in all our lives is transitory. Every other good is visionary. But the acts of love which no one knows about, or can ever know about – they never fail.
