Matthew 6:27

Wherefore neither did He simply say, "Take no thought what ye shall eat," or "wherewithal ye shall be clothed;" but, "for the body," and, "for the soul:" forasmuch as from them He was to make His demonstrations, carrying on His discourse in the way of comparison. Now the soul He hath given once for all, and it abides such as it is; but the body increases every day. Therefore pointing out both these things, the immortality of the one, and the frailty of the other, He subjoins and says, "Which of you can add one cubit unto his stature?" Thus, saying no more of the soul, since it receives not increase, He discoursed of the body only; hereby making manifest this point also, that not the food increases it, but the providence of God. Which Paul showing also in other ways, said, "So then, neither is he that planteth any thing, neither he that watereth; but God that giveth the increase."

But if thou canst not bear, upon hearing so high words, to release thyself from these grievous bonds, consider the unprofitableness of the thing, and so put an end to thy care. For "Which of you by taking thought" (saith He) "can add one cubit unto his stature." Seest thou how by that which is evident, He hath manifested that also which is obscure? Thus, "As unto thy body," saith He, "thou wilt not by taking thought be able to add, though it be ever so little; so neither to gather food; think as thou mayest otherwise." Hence it is clear that not our diligence, but the providence of God, even where we seem to be active, effects all. So that, were He to forsake us, no care, nor anxiety, nor toil, nor any other such thing, will ever appear to come to anything, but all will utterly pass away. Let us not therefore suppose His injunctions are impossible: for there are many who duly perform them, even as it is. And if thou knowest not of them, it is nothing marvellous, since Elias too supposed he was alone, but was told, "I have left unto myself seven thousand men." Whence it is manifest that even now there are many who show forth the apostolical life; like as the "three thousand" then, and the "five thousand." And if we believe not, it is not because there are none who do well, but because we are far from so doing. […]

(Serm. in Mont. ii. 15.) Or it may be connected with what follows it; as though He should say, It was not by our care that our body was brought to its present stature; so that we may know that if we desired to add one cubit to it, we should not be able. Leave then the care of clothing that body to Him who made it to grow to its present stature.

(De Civ. Dei, xxii. 15.) But if Christ rose again with the same stature with which He died, it is impious to say that when the time of the resurrection of all shall come, there shall be added to His body a bigness that it had not at His own resurrection, (for He appeared to His disciples with that body in which He had been known among them,) such that He shall be equalled to the tallest among men. If again we say that all men's bodies, whether tall or short, shall be alike brought to the size and stature of the Lord's body, then much will perish from many bodies, though He has declared that not a hair shall fall. It remains therefore that each be raised in his own stature—that stature which he had in youth, if he died in old age; if in childhood that stature to which he would have attained had he lived. For the Apostle says not, 'To the measure of the stature,' but, To the measure of the full age of Christ. (Eph. 4:13.) For the bodies of the dead shall rise in youth and maturity to which we know that Christ attainedd.

And which of you by taking thought, can add to his stature one cubit? He draws an argument from experience. For it is manifest that just as God provides for animals in the works of nature, so also for men. For in man there is …

(non occ.) He teaches us not only by the instance of the birds, but adds a further proof, that to our being and life our own care is not enough, but Divine Providence therein works; saying, Which of you by taking thought can add one cubit to his stature?

"Which of you by taking thought can add one cubit unto his stature?" This means, even if you take the utmost care, you can do nothing if God does not will it. Why then do you drive yourself to exhaustion with futile worries?

Which of you by taking thought,.... As Christ argued before, from the unnecessariness of anxious thoughts and cares, about the provisions of life; so here, from the unprofitableness of them; it being impossible for a man, with all his care and thought, to add one cubit unto his stature, or "to his age"; so the word is rendered, Joh 9:21 to the days of his life, he is so solicitous about; for a cubit may as well be applied to a man's age, as an "hand's breadth" is to his days, Psa 39:

Which of you, by taking thought - The third argument is taken from their extreme weakness and helplessness. With all your care you cannot increase your stature a single cubit. God has ordered your height. Beyond his appointment your powers are of no avail, and you can do nothing. So of raiment. He, by His providence, orders and arranges the circumstances of your life. “Beyond” that appointment of His providence, beyond his care for you, your efforts avail nothing.

These verses are a striking example of the combined wisdom and compassion of our Lord Jesus Christ’s teaching. He knows the heart of a man: he knows that we are always ready to turn off warnings against worldliness by the argument that we cannot help being anxious about the things of this life. “Have we not our families to provide for? Must not our bodily wants be supplied? How can we possibly get through life if we think first of our souls?” The Lord Jesus foresaw such thoughts and furnished an answer.

These verses are a striking example of the combined wisdom and compassion of our Lord Jesus Christ’s teaching. He knows the heart of a man: he knows that we are always ready to turn off warnings against worldliness by the argument that we cannot help being anxious about the things of this life. “Have we not our families to provide for? Must not our bodily wants be supplied? How can we possibly get through life if we think first of our souls?” The Lord Jesus foresaw such thoughts and furnished an answer. He forbids us to keep up an anxious spirit about the things of this world. Four times over he says, “Take no thought about life.”About life, about food, about clothing, about the morrow, “take no thought.” Do not be over-careful, be not over-anxious. Prudent provision for the future is right; wearing, corroding, self-tormenting anxiety is wrong. He reminds us of the providential care that God continually takes of everything that he has created. Has he given us “life?” Then he will surely not let us want anything necessary for its maintenance. Has he given us a “body?”Then he will surely not let us die for want of clothing. He that calls us into being will doubtless find meat to feed us. He points out the uselessness of over-anxiety. Our life is certainly in God’s hand; all the care in the world will not make us continue a minute beyond the time which God has appointed. We cannot add one hour to our lives; we shall not die till our work is done. He sends us to the birds of the air for instruction. They make no provision for the future: “they sow not neither do they reap; they lay up no stores against time yet to come; they do not gather into barns.They literally live from day to day on what they can pick up by using the instinct God has put in them.

Which of you by taking thought can add one cubit unto his stature? - The third reason against these carking cares is the unprofitableness of human solicitude, unless God vouchsafe to bless it. What can our uneasiness do but render us still more unworthy of the Divine care? The passage from distrust to apostasy is very short and easy; and a man is not far from murmuring against Providence, who is dissatisfied with its conduct. We should depend as fully upon God for the preservation of his gifts as for the gifts themselves. Cubit unto his stature? - I think ηλικιαν should be rendered age here, and so our translators have rendered the word in Joh 9:21, αυτος ηλικιαν εχει he is of age. A very learned writer observes, that no difficulty can arise from applying πηχυν a cubit, a measure of extension, to time, and the age of man: as place and time are both quantities, and capable of increase and diminution, and, as no fixed material standard can be employed in the mensuration of the fleeting particles of time, it was natural and necessary, in the construction of language, to apply parallel terms to the discrimination of time and place. Accordingly, we find the same words indifferently used to denote time and place in every known tongue. Lord, let me know the Measure of my days! Thou hast made my days Hand-Breadths, Psa 39:5. Many examples might be adduced from the Greek and Roman writers. Besides, it is evident that the phrase of adding one cubit is proverbial, denoting something minute; and is therefore applicable to the smallest possible portion of time; but, in a literal acceptation, the addition of a cubit to the stature, would be a great and extraordinary accession of height.
