C.S. Lewis wrote this to a friend.
…I dined at the Harwoods that night and came away—on Tuesday morning—as you said in your last letter ‘thanking the Giver’ which, by the way, is the completion of a pleasure. One of the things about being an unbeliever is that the steam or ‘spirit’ (in the chemical sense) given off by experiences has nowhere to go to.
In a true sense, thankfulness is the acknowledgement and completion of a pleasure or a gift. The failure to thank a gift-giver robs both the giver and receiver of completion. Similarly, so does the failure of internal gratitude also deny the fruition and flowering of the gift into its full potential/completion within us.
So today, let us recommit ourselves to a spirit of thankfulness and gratitude. Then our gardens will flourish with the manifestations of God’s will and the recognition of all our blessings and gifts. Our full pleasure will then be complete.
In thankful gratitude,
Z gardener
