Luke 9:24

(ut sup.) He assigns the cause of this when He adds, For whosoever will save his life shall lose it; that is, whosoever will according to the present life keep his own soul fixed on things of sense, the same shall lose it, never reaching to the bounds of happiness. But on the other hand He adds, but whosoever shall lose his life for my sake, shall save it. That is, whosoever forsakes the things of sense looking upon truth, and exposes himself to death, as it were losing his life for Christ, shall the rather save it. If then it is a blessed thing to save our life, (with regard to that safety which is in God,) there must be also a certain good surrender of life which is made by looking upon Christ. It seems also to me from resemblance to that denying of one's self which has been before spoken of, that it becomes us to lose a certain sinful life of ours, to take up that which is saved by virtue.

(Hom. 32. in Ev.) Since then the holy Church has one time of persecution, another time of peace, our Lord has noticed both times in His command to us. For at the time of persecution we must lay down our soul, that is our life, which He signified, saying, Whosoever shall lose his life. But in time of peace, those things which have the greatest power to subdue us, our earthly desires, must be vanquished; which He signified, saying, What does it profit a man, &c. Now we commonly despise all fleeting things, but still we are so checked by that feeling of shame so common to man, that we are yet unable to express in words the uprightness which we preserve in our hearts. But to this wound the Lord indeed subjoins a suitable application, saying, For whoever shall be ashamed of me and my words, of him shall the Son of man be ashamed.

Now our Lord while He ever raises us to look to the future reward of virtue, and teaches us how good it is to despise worldly things, so also He supports the weakness of the human mind by a present recompense. For it is a hard thing to take up the cross, and expose your life to danger and your body to death; to give up what you are, when you wish to be what you are not; and even the loftiest virtue seldom exchanges things present for future. The good Master then, lest any man should be broken down by despair or weariness, straightway promises that He will be seen by the faithful, in these words, But I say unto you, There are some standing here who shall not taste of death till they see the kingdom of God.
