Matthew 6:1111Give us this day our daily bread. (Matthew 6:11); Luke 11:33Give us day by day our daily bread. (Luke 11:3); Exodus 16:15-2415And when the children of Israel saw it, they said one to another, It is manna: for they wist not what it was. And Moses said unto them, This is the bread which the Lord hath given you to eat. 16This is the thing which the Lord hath commanded, Gather of it every man according to his eating, an omer for every man, according to the number of your persons; take ye every man for them which are in his tents. 17And the children of Israel did so, and gathered, some more, some less. 18And when they did mete it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating. 19And Moses said, Let no man leave of it till the morning. 20Notwithstanding they hearkened not unto Moses; but some of them left of it until the morning, and it bred worms, and stank: and Moses was wroth with them. 21And they gathered it every morning, every man according to his eating: and when the sun waxed hot, it melted. 22And it came to pass, that on the sixth day they gathered twice as much bread, two omers for one man: and all the rulers of the congregation came and told Moses. 23And he said unto them, This is that which the Lord hath said, To morrow is the rest of the holy sabbath unto the Lord: bake that which ye will bake to day, and seethe that ye will seethe; and that which remaineth over lay up for you to be kept until the morning. 24And they laid it up till the morning, as Moses bade: and it did not stink, neither was there any worm therein. (Exodus 16:15‑24)
A man can no more take in a supply of grace for the future than he can eat enough today to last him for the next six months; or take sufficient air into his lungs at once to sustain life for a week to come. We must draw upon God’s boundless stores of grace from day to day, as we need it.
