Take therefore no thought for tomorrow: for tomorrow shall take thought of the things for itself. Sufficient unto the day is the evil thereof.
All Commentaries on Matthew 6:34 Go To Matthew 6
John Chrysostom
AD 407
Nothing brings so much pain to the spirit as anxiety and cark. That He says, "The morrow shall be anxious for itself,” comes of desire to make more plain what He speaks; to that end employing a prosopopeia of time, after the practice of many in speaking to the rude populace; to impress them the more, He brings in the day itself complaining of its too heavy cares. Has not every day aburden enough of its own, in its own cares? why then do you add to them by laying on those that belong to another day?.
Otherwise; By “today” are signified such things as are needful for us in this present life; “Tomorrow” denotes those things that are superfluous. “Be not yetherefore anxious for the morrow,” thus means, Seek not to have aught beyond that which is necessary for your daily life, for that which is over and above, i.e. Tomorrow, shall care for itself. "Tomorrow shall be anxious for itself,” isas much as to say, when you have heaped up superfluities, they shall care for themselves, you shall not enjoy them, but they shall find many lords who shall care for them. Why then should you be anxious about those things, the property of which you must part with? "Sufficient for the day is its own evil, "as much as to say, The toil you undergo for necessaries is enough, do not toil for things superfluous.
