John 12:24-25

I assure you and most solemnly say to you, unless a grain of wheat falls into the earth and dies, it remains alone [just one grain, never more]. But if it dies, it produces much grain and yields a harvest. The one who loves his life [eventually] loses it [through death], but the one who hates his life in this world [and is concerned with pleasing God] will keep it for life eternal.
