“I have observed many persons rejoicing, and saying one to another, ‘We have conquered; we have prevailed; the half of the fast is spent.’ But I exhort such persons not to rejoice on this account, that the half of the fast is gone, but to consider whether the half of their sins be gone; and if so, then to exult. For this is a fit subject of gratification. This is what is to be sought after, and for which all things are done, that we may correct our defects; and that we may not quit the fast the same persons as we entered upon it, but in a cleansed state; and that having laid aside all that belongs to evil habits, we may thus keep the sacred feast, since if the case be otherwise, we shall be so far from obtaining any advantage, that the completion of the fast will be the greatest injury to us. Let us, therefore, not rejoice that we have gone through the length of the fast, for this is nothing great; but let us rejoice, if we have got through it with fresh attainments, so that when this is over, the fruit of it may shine forth. For the gain of winter is more especially manifested after the season is gone by.
Then, the flourishing corn, and the trees teeming with leaves and fruit, proclaim, by their appearance, the benefit that has accrued to them from the winter! Let the same thing also take place with us. For during the winter, we have enjoyed divers and frequent showers, having been during the fast partakers of a continued course of instruction, and have received spiritual seeds, and cut away the thorns of luxury.” (St. John Chrysostom, Rejoice in the Lord Always, p. 2)
