from Diary of an Old Soul, by George MacDonald

When I can no more stir my soul to move,
And life is but the ashes of a fire;
When I can but remember that my heart
Once used to live and love, long and aspire --
Oh be thou then the first, the one thou are;
Be thou the calling, before all answering love,
And in me wake hope, fear, boundless desire.
