Luke 9:26

Now he strikes fear into their hearts, when He says that He will descend from heaven, not in His former humility and condition proportioned to our capacities for receiving Him, but in the glory of the Father, with the Angels ministering unto Him. For it follows, When he shall come in his own glory, and his Father's, and of the holy angels. Awful then and fatal will it be, to be branded as an enemy, and slothful in business, when so great a Judge shall descend with the armies of Angels standing round Him. But from this you may perceive, that though He has taken to Himself our flesh and blood, the Son is no less God, seeing that He promises to come in the glory of God the Father, and that Angels shall minister to Him as the Judge of all, Who was made man like unto us.

(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.

He is ashamed of Christ who says, Am I to believe on Him that is crucified? He also is ashamed of His words who despises the simplicity of the Gospel. But of him shall the Lord be ashamed in His kingdom, in the same manner as if a master of a household should have a bad servant, and be ashamed to have him.

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.
