He that loves his life shall lose it; and he that hates his life in this world shall keep it unto life eternal.
All Commentaries on John 12:25 Go To John 12
Cyril of Alexandria
AD 444
You not only ought not to be offended at the thought of My suffering, or to disbelieve the words I said, but it is even right that you should be prepared in anticipation of it; for he that thinks fit to be careful over his life here, and is not willing to expose it to dangers for My sake, loses it in the time to come. But he who exposes it to dangers in this present world is laying up in store for it great rewards. And he who despises his life in this world shall obtain in the world to come life incorruptible. And the Lord said these words, not as implying that the life [i. e. the soul] can suffer anything here, but meaning by "love of life" the disposition to hold it firmly, as shown by those who do not expose their body to dangers.
