Luke 9:25

But that incomparable exercise of the passion of Christ, which surpasses the delights and precious things of the world, is alluded to when he adds, What is a man advantaged, if he gain the whole world and lose himself, or be a cast away? As if he says, When a man, through his looking after the present delights, gains pleasure, and refuses indeed to suffer, but chooses to live splendidly in his riches, what advantage will he get then, when he has lost his soul? For the fashion of this world passeth away, and pleasant things depart as a shadow. (1 Cor. 7:31. Sap. 5:9.) For the treasures of ungodliness shall not profit, but righteousness snatches a man from death. (Prov. 10:2.)

(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.
