John 12:25
Anyone who loves their life will lose it, while anyone who hates their life in this world will keep it for eternal life — Jesus extends the principle from His own necessary death to the universal requirement of discipleship: attachment to earthly life (philia tēs psychēs, love of one's life/soul) results in loss; renunciation of worldly life leads to eternal life (zōē aiōnios). The paradox of losing to gain is central to Christian discipleship.
