Finally, Christ here tells us, that thought for the morrow is contrary to all the scheme of Providence, which shows it to be vain. The morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.'
I interpret these two clauses as meaning this:
To-morrow has anxieties enough of its own, after and in spite of all the anxieties about it to-day by which you try to free it from care when it comes. Every day --every day will have its evil, have it to the end. And every day will have evil enough to task all the strength that a man has to cope with it. So that it just comes to this: Anxiety,--it is all vain. After all your careful watching for the corner of the heaven where the cloud is to come from, there will be a cloud, and it will rise somewhere, but you never know beforehand from what quarter. The morrow shall have its own anxieties. After all your fortifying of the castle of your life, there will be some little postern left unguarded, some little weak place in the wall left uncommanded by a battery; and there, where you never looked for him, the inevitable invader will come in. After all the plunging of the hero in the fabled waters that made him invulnerable, there was the little spot on the heel, and the arrow found its way there! There is nothing certain to happen, says the proverb, but the unforeseen. To-morrow will have its cares, spite of anything that anxiety and foreboding can do. It is God's law of Providence that a man shall be disciplined by sorrow; and to try to escape from that law by any forecasting prudence, is utterly hopeless, and madness.
And what does your anxiety do? It does not empty to-morrow, brother, of its sorrows; but, all! it empties to-day of its strength. It does not enable you to escape the evil, it makes you unfit to cope with it when it comes. It does not bless to-morrow, but it robs to-day. For every day has its own burden. Sufficient for each day is the evil which properly belongs to it. Do not add to-morrow's to to-day's. Do not drag the future into the present. The present has enough to do with its own proper concerns. We have always strength to bear the evil when it comes. We have not strength to bear the foreboding of it. As thy day, thy strength shall be.' In strict proportion to the existing exigencies will be the God-given power; but if you cram and condense to-day's sorrows by experience, and to-morrow's sorrows by anticipation, into the narrow round of the one four-and-twenty hours, there is no promise that as that day thy strength shall be.' God gives us (His name be praised!)--God gives us power to bear all the sorrows of His making; but He does not give us power to bear the sorrows of our own making, which the anticipation of sorrow most assuredly is.
Then: contrary to the lessons of Nature, contrary to the teachings of Religion, contrary to the scheme of Providence; weakening your strength, distracting your mind, sucking the sunshine out of every landscape, and casting a shadow over all the beauty--the curse of our lives is that heathenish, blind, useless, faithless, needless anxiety in which we do indulge. Look forward, my brother, for God has given you that royal and wonderful gift of dwelling in the future, and bringing all its glories around your present. Look forward, not for life, but for heaven; not for food and raiment, but for the righteousness after which it is blessed to hunger and thirst, and wherewith it is blessed to be clothed. Not for earth, but for heaven, let your forecasting gift of prophecy come into play. Fill the present with quiet faith, with patient waiting, with honest work, with wise reading of God's lessons of nature, of providence, and of grace, all of which say to us, Live in God's future, that the present may be bright: work in the present, that the future may be certain! They may well look around in expectation, sunny and unclouded, of a blessed time to come, whose hearts are already' fixed, trusting in the Lord.' He to whom there are a present Christ, and a present Spirit, and a present Father, and a present forgiveness, and a present redemption, may well live expatiating in all the glorious distance of the unknown to come, sending out (if I may use such a figure) from his placid heart over all the weltering waters of this lower world, the peaceful seeking dove, his meek hope, that shall come back again from its flight with some palm-branch broken from the trees of Paradise between its bill. And he that has no such present has a future dark, chaotic, a heaving, destructive ocean; and over it there goes for ever--black-pinioned, winging its solitary and hopeless flight--the raven of his anxious thoughts, which finds no place to rest, and comes back again to the desolate ark with its foreboding croak of evil in the present and evil in the future. Live in Christ, the same yesterday, and today, and for ever'; and His presence shall make all your past, present, and future--memory, enjoyment, and hope--to be bright and beautiful, because all are centred in Him.
