Psalms 102:24

Let not therefore heretics flatter themselves against me, because I said, "the shortness of my days," as if they would not last down to the end of the world. For what has he added? "O my God, take me not away in the midst of my days" [Psalm 102:24]. Deal Thou not with me according as heretics speak. Lead me on unto the end of the world, not only to the middle of my days; and finish my short days, that You may afterwards grant unto me eternal days. Wherefore then have you asked concerning the shortness of your days? Wherefore? Do you wish to hear? "Your years are in the generation of generations." This is why I asked concerning those short days, because although my days should endure unto the end of the world, yet they are short in comparison of Your days. For "Your years are in the generation of generations." Wherefore does he not say, Your years are unto worlds of worlds; for thus rather is eternity usually signified in the holy Scriptures; but he says, "Your years are in the generation of generations"? But what are your years? What, but those which do not come, and then pass away? What, but they which come not, so as to cease again? For every day in this season so comes as to cease again; every hour, every month, every year; nothing of these is stationary; before it has come, it is to be; after it has come, it will not be. Those everlasting years of yours, therefore, those years that are not changed, "are in the generation of generations." There is a "generation of generations;" in that shall your years be. There is one such, and if we acknowledge it aright, we shall be in it, and the years of God shall be in us. How shall they be in us? Just as God Himself shall be in us: whence it is said, "That God may be all in all." [1 Corinthians 15:28] For the years of God, and God Himself, are not different: but the years of God are the eternity of God: eternity is the very substance of God, which has nothing changeable; there nothing is past, as if it were no longer: nothing is future, as if it existed not as yet. There is nothing there but, Is: there is not there, Was, and Will be; because what was, is now no longer: and what will be, is not as yet: but whatever is there, simply Is....Behold this great I Am! What is man's being to this? To this great I Am, what is man, whatever he be? Who can understand that To Be? Who can share it? Who can pant, aspire, presume that he may be there? Despair not, human frailty! "I am," He says, "the God of Abraham, and the God of Isaac, and the God of Jacob." You have heard what I am in Myself: now hear what I am on your account. This eternity then has called us, and the Word burst forth from eternity. It is now eternity, it is now the Word, and no longer time.
