Count all things but loss

"He is no fool who gives what he cannot keep to gain what he cannot lose."
~Jim Elliot


But what things were gain to me, those I counted loss for Christ.
Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,  ~Philippians 3:8
