Matthew 6:34

Take therefore no thought. See on v. 25. Christians can be free from anxiety in the midst of the most distressing circumstances, fully assured that He who does everything well (cf. Mark 7:37) will make all things “work together for good” (Rom. 8:28). God knows all about tomorrow; we know not “what a day may bring forth” (Prov. 27:1). And He who knows all about tomorrow bids us to trust in His continued watchcare and to “take ... no [anxious] thought” concerning its problems and perplexities. When tomorrow comes, its anticipated troubles often prove to have been wholly imaginary. Too many people permit themselves to be haunted by the ghost of tomorrow before tomorrow ever comes.

Christians should ever remember that God does not bestow help for tomorrow’s burdens until tomorrow comes; and it is their privilege to learn each passing day the truth of Christ’s words to Paul, “My grace is sufficient for thee” (2 Cor. 12:9; cf. ch. 4:16).

Sufficient unto the day. “Why worry about tomorrow?” Christ inquires. “Tomorrow will take care of itself when it comes.” Each day brings its own measure of toil and care, and wise is the man who learns not to try to bear tomorrow’s burdens today.

The evil thereof. Or, “the day’s own trouble” (RSV). See Prov. 27:1.
