but i've thought alot about it lately:
Nothing that you have not given away will ever be really yours.
- C.S. Lewis
Looking it up I find that it's in Mere Christianity. Which I find a bit funny as I don't like apologetics much. Here is the excerpt:
The principle runs through all life from top to bottom. Give up yourself, and you will find your real self. Lose your life and you will save it. Submit to death, death of your ambitions and favorites wishes every day and death of your whole body in the end: submit with every fibre of your being, and you will find eternal life. Keep back nothing. Nothing that you have not given away will ever be really yours. Nothing in you that has not died will ever be raised from the dead. Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ, and you will find Him, and with Him everything else thrown in.
