Psalms 102:15

19. “Man, his days are but as grass” ( ver. 15 ). Let man consider what he is; let not man be proud. “His days are but as grass.” Why is the grass proud, that is now flourishing, and in a very short space dried up? Why is the grass proud that flourisheth only for a brief season, until the sun be hot? It is then good for us that His mercy be upon us, and from grass make gold. “For he flourisheth as a flower of the field.” The whole splendour of the human race; honour, powers, riches, pride, threats, is the flower of the grass. That house flourisheth, and that family is great, that family flourisheth; and how many flourish, and how many years do they live! Many years to thee, are but a short season unto God. God doth not count, as thou dost. Compared with the length and long life of ages, all the flower of any house is as the flower of the field. …

11. The admonition however, and the counsel, such as it is, appears to some to give authority for drinking wine too freely. But this is not so. If indeed we closely investigate this very saying, it rather amounts to a recommendation of abstinence. For just consider that Paul did not at first, nor at the outset give this counsel. But when he saw that all strength was overthrown, then he gave it; and even then not simply, but with a certain prior limitation. He does not say merely, “Use wine,” but “a little” wine; not because Timothy needed this admonition and advice, but because we need it. On this account, in writing to him, he prescribes the measure and limit of wine-drinking for us; bidding him drink just so much as would correct disorder; as would bring health to the body, but not another disease. …

But having a sample in what I have mentioned, ye will have a notion of all the rest besides, the things about Christ, about the resurrection, about the life to come, about the resting, about punishment, about moral matters, all that concerns doctrines, and you will find the book filled with countless blessings. And if you fall into temptations, you will gain much comfort from hence. If you fall into sins even, you will find countless remedies stored up here, or if into poverty or tribulation, you will see many havens. And if thou be righteous thou wilt gain much security hence, and if a sinner much relief. For if thou be just and art ill-treated, thou wilt hear him say, “For Thy sake are we killed all the day long, we are counted as sheep for the slaughter.” ( Ps. xliv. 22 .) “All these things have come upon us, and yet have we not forgotten Thee.” ( ib. …

19. Such, my brethren, is our existence, who live this transient life, such our pastime upon earth: we come into existence out of non-existence, and after existing are dissolved. We are unsubstantial dreams, impalpable visions, like the flight of a passing bird, like a ship leaving no track upon the sea, a speck of dust, a vapour, an early dew, a flower that quickly blooms, and quickly fades. As for man his days are as grass, as a flower of the field, so he flourisheth. …

29. But concerning the Resurrection more will be said later on; let us now return to our immediate subject. We have set forth that even holy men have without any consideration for their merits, suffered many and heavy things in this world, together with toil and misery. So David, entering into himself, says: “Remember; Lord, that we are dust; as for man, his days are but as grass;” and in another place: “Man is like to vanity, his days pass away as a shadow.” For what is more wretched than we, who are sent into this life as it were plundered and naked, with frail bodies, deceitful hearts, weak minds, anxious in respect of cares, slothful as to labour, prone to pleasures.
