Give us our daily bread...

2 Corinthians 8:13-15 13 I do not mean that others should be eased and you burdened, but that as a matter of fairness 14 your abundance at the present time should supply their need, so that their abundance may supply your need, that there may be fairness. 15 As it is written, "Whoever gathered much had nothing left over, and whoever gathered little had no lack."

This passage is actually dealing with how the churches at Corinth, Macedonia and Achaia were supplying monetary provision for the needs of the others

But look at the quoted passage from the OT:
Exodus 16:15-18 15 When the people of Israel saw it, they said to one another, "What is it?" For they did not know what it was. And Moses said to them, "It is the bread that the LORD has given you to eat. 16 This is what the LORD has commanded: 'Gather of it, each one of you, as much as he can eat. You shall each take an omer, according to the number of the persons that each of you has in his tent.'" 17 And the people of Israel did so. They gathered, some more, some less. 18 But when they measured it with an omer, whoever gathered much had nothing left over, and whoever gathered little had no lack. Each of them gathered as much as he could eat.

It implies that the Lord has given His church their daily bread as a whole
everyone has been given sufficient for what the day needs and not for the next
yet some gathered more, and others less - but no one had more than one omer per person
implying that the global church has been granted sufficient resources for all it needs, yet the distribution of resources has been different - such that some may learn to be humbled and ask, others may learn to be generous and give
if then there is lack - it is the fault of the church, not the Lord

so then James says:
James 5:1-6 Come now, you rich, weep and howl for the miseries that are coming upon you. 2 Your riches have rotted and your garments are moth-eaten. 3 Your gold and silver have corroded, and their corrosion will be evidence against you and will eat your flesh like fire. You have laid up treasure in the last days. 4 Behold, the wages of the laborers who mowed your fields, which you kept back by fraud, are crying out against you, and the cries of the harvesters have reached the ears of the Lord of hosts. 5 You have lived on the earth in luxury and in self-indulgence. You have fattened your hearts in a day of slaughter. 6 You have condemned; you have murdered the righteous person. He does not resist you.

his accusation is against the rich of the visible church that store up the manna - indeed it has rotted in their bank accounts! and the rest of the church is now crying out..

Lord forgive us for holidng back and show us how to give in love, generosity and abundance that all may have need - and trust the provision of the Lord

no wonder it the prayer is "our Father" "give us our daily bread"
