(26) If ye then be not able to do that thing which is least.--The words are peculiar to St. Luke's report. If no amount of anxious care can add one cubit to our stature or the measure of our days (see Notes on Matthew 6:27), how much less can we control all the myriad contingencies upon which the happiness of the future may depend!

12:22-40 Christ largely insisted upon this caution not to give way to disquieting, perplexing cares, Mt 6:25-34. The arguments here used are for our encouragement to cast our care upon God, which is the right way to get ease. As in our stature, so in our state, it is our wisdom to take it as it is. An eager, anxious pursuit of the things of this world, even necessary things, ill becomes the disciples of Christ. Fears must not prevail; when we frighten ourselves with thoughts of evil to come, and put ourselves upon needless cares how to avoid it. If we value the beauty of holiness, we shall not crave the luxuries of life. Let us then examine whether we belong to this little flock. Christ is our Master, and we are his servants; not only working servants, but waiting servants. We must be as men that wait for their lord, that sit up while he stays out late, to be ready to receive him. In this Christ alluded to his own ascension to heaven, his coming to call his people to him by death, and his return to judge the world. We are uncertain as to the time of his coming to us, we should therefore be always ready. If men thus take care of their houses, let us be thus wise for our souls. Be ye therefore ready also; as ready as the good man of the house would be, if he knew at what hour the thief would come.If ye then be not able to do that which is least,.... As to make the smallest addition to a man's stature, or rather to add one moment to his days:

why take ye thought for the rest? which are much greater, as to preserve the body in its whole bulk, and all its parts, or for the feeding and clothing of it, or rather for the continuation and preservation of life to any length of time; for if it cannot be by all a man's care and solicitude lengthened out one moment longer than is the pleasure of God, how should it be by such anxiety continued for months and years?
