"Those who love their life in this world will lose it. Those who care nothing for their life in this world will keep it for eternity." (John 12:25)
"We have our choice. We may live for self, take good care of our lives, not exposing them to danger, not making sacrifices, looking out for our own interests, and we may prosper in the world; people will commend our prudence and congratulate us on our success. We may reach old age hail and well preserved, and greatly enjoy our accumulated honours and possessions. This is one way of living...
The other way is to forget self; not to think of nor care for one's own life, but to throw it away in obedience to God and unselfish service. People will say you are foolish thus to waste your golden life, thus to sacrifice yourself for the sake of the others or in Christ's cause. But was Christ Himself foolish when he went to the cross? Let the redeemed church be the answer."
