Thank him that His hands hold it, and not your feeble, uncertain fingers.
Longfellow wrote nothing more elevating and helpful than his sonnet to "To-morrow, the Mysterious Guest," who whispers to the boding human soul: "'Remember Barmecide, And tremble to be happy with the rest.' And I make answer, 'I am satisfied.
I know not, ask not, what is best; God hath already said what shall betide.'" The new version of the New Testament, among other richly suggestive readings, tells us that Martha was "_distracted_ with much serving," and that we are not to be "anxious for the morrow; for the morrow will be anxious for itself." That is, it will bring its own proper load of labor and of care, from which you have no right to borrow for to-day's uses; which you cannot diminish by the same process.
George MacDonald puts this great principle aptly: "You have a disagreeable duty to do at twelve o'clock.

Do not blacken nine, and ten and eleven with the color of twelve.

Do the work of each and reap your reward in peace." One woman makes it her boast that she never sets bread for the morning that she does not lie awake half the night wondering how it will "turn out." She is so besotted in her ignorance as to think that the useless folly proves her to be a person of exquisite sensibility, whereas it testifies to lack of self-control, common sense and economical instincts.
It was old John Newton who likened the appointed tasks and trials of men to so many logs of wood, each lettered with the name of the day of the week, and no single one of them too heavy to be borne by a mortal of ordinary strength.

If we will persist; he went on to say, in adding Tuesday's stick to Monday's, and Wednesday's and Thursday's and Friday's to that marked for Tuesday, "it is small wonder that we sink beneath the burden." Our Heavenly Father would have us carry one stick at a time, and for this task has regulated our systems--mental, moral and spiritual.

We, like the presumptuous bunglers that we are, bind the sticks into faggots, and then whine because our strength gives out.
The lesson of unlearning what we have practiced so long is not easy, but it may be acquired.
