Thanksgiving seems particularly suitable for those who have torn out of their hearts the sins which pricked their conscience and are at last free from fear of falling again: and then, recollecting the generosity and the mercy of the Lord, past or present or future, are rapt away into that spark-like prayer which no mortal can understand or describe.
