Mine, Mine, Mine: by CS Lewis (from The Screwtape Letters)

every animal of the forest is mine, and the cattle on a thousand hills. Psalm 50:10
 Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own;  you were bought at a price. Therefore honor God with your body. 1 Corinthians 6:19-20

Screwtape acknowledges the truth about ownership:

Even in the nursery a child can be taught to mean by 'my teddy bear' not the old imagined recipient of affection to whom it stands in a special relation (for that is what the Enemy will teach them to mean if we are not careful) but 'the bear I can pull to pieces if I like'. And at the other end of the scale, we have taught men to say 'my God' in a sense not really very different from 'my boots', meaning 'the God on whom I have a claim for my distinguished services and whom I exploit from the pulpit—the God I have done a corner in'.

And all the time the joke is that the word 'Mine' in its fully possessive sense cannot be uttered by a human being about anything. In the long run either Our Father or the Enemy will say 'Mine' of each thing that exists, and specially of each man. They will find out in the end, never fear, to whom their time, their souls, and their bodies really belong—certainly not to them, whatever happens. At present the Enemy says 'Mine' of everything on the pedantic, legalistic ground that He made it: Our Father hopes in the end to say 'Mine' of all things on the more realistic and dynamic ground of conquest.
