Speaking to the people, Jesus continued, “Be alert and guard your heart from greed and always wishing for what you don’t have. For your life can never be measured by the amount of things you possess.” (Luke 12.15, Passion Translation)

I don’t know who said this first, but it’s common now…

For whoever wants to save their life will lose it, but whoever loses their life for me will save it. What good is it for someone to gain the whole world, and yet lose or forfeit their very self? (Luke 9.24, 25, NIV)

He is no fool who gives what he cannot keep to gain what he cannot lose. – Jim Elliott
