Matthew 6:34 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
Take therefore no thought ... - That is, no anxiety. Commit your way to God. The evil, the trouble, the anxiety of each day as it comes, is sufficient without perplexing the mind with restless cares about another day. It is wholly uncertain whether you live to see another day. If you do, it will bring its own trouble, and it will also bring the proper supply of your needs. God will be the same Father then as today, and will make then, as he does now, proper provision for your wants.
The morrow shall take thought - The morrow will have anxieties and cares of its own, but it will also bring the proper provision for those cares. Though you will have needs, yet God will provide for them as they occur. Do not, therefore, increase the cares of today by borrowing trouble from the future. Do your duty faithfully now, and depend upon the mercy of God and his divine help for the troubles which are yet to come. Barnes.
