The above quotation is from a precious verse in Matt. 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.
From this we learn the needed lesson not to bring the “evil” of tomorrow into today—not to foredate sorrow. We have only to live by the day, and we shall find God's grace amply sufficient for the need of each day as it arises. But if we attempt to grapple today with the anticipated difficulties of tomorrow, we must do so at our own charges and shall not be able to meet the demand.
“Let each day upon its wing,
Its allotted burden bring;
Load it not, beside, with sorrow
That belongeth to tomorrow.
Strength is promised, strength is given,
When the heart by God is riven;
But foredate the date of woe,
And alone thou bear'st the blow.”
