Matthew 16:26
For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul? The soul-profit question is the challenge of the kingdom's economics applied to the individual: the entire world's wealth cannot compensate for the soul's loss. The soul is the irreplaceable self — the person as known by God — and no accumulation of the world's goods can substitute for it.
