Lose your life and you will save it. Submit to death, death of your ambitions and favorite wishes every day, and death to your whole body in the end: submit with every fiber of your being, and you will find eternal life. Keep back nothing. Nothing that you have not given away will be really yours. Nothing in you that has not died will 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.
