It is also suggested here and here that this is more than just a temporary measure during the time of the Olympics but an attempt to use the situation to argue for a repeal of the Sunday Trading laws altogether.
Sabbath desecration is closely tied to national decline. The mistaken idea that more opening hours means more money spent and more prosperity for business, which means more jobs for citizens and more money to spent in shops etc is a deeply flawed argument. This reasoning is based solely on economics.
However, this flawed argument forgets to take on board that there is another law, a moral law, that also operates in this world, whether governments or citizens acknowledge it or not. That moral law states that instead of advancing the prosperity of a nation Sunday Trading brings national decline.
Nehemiah forthrightly told the 'Sunday Traders' this in Nehemiah13:18:
Did not your fathers thus, [buy and sell, see vv15-21] and did not our God bring all this evil upon us, and upon this city? yet ye bring more wrath upon Israel by profaning the sabbath.
These 'Sunday Traders' in Nehemiah's day had not learned the lesson from previous times. Both in Jeremiah's and in Ezekiel's days this same truth was pressed upon the people of Israel.
Jeremiah 17:21-27 reads:
Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem;
Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers.
But they obeyed not, neither inclined their ear, but made their neck stiff, that they might not hear, nor receive instruction.
And it shall come to pass, if ye diligently hearken unto me, saith the LORD, to bring in no burden through the gates of this city on the sabbath day, but hallow the sabbath day, to do no work therein;
Then shall there enter into the gates of this city kings and princes sitting upon the throne of David, riding in chariots and on horses, they, and their princes, the men of Judah, and the inhabitants of Jerusalem: and this city shall remain for ever.
And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and meat offerings, and incense, and bringing sacrifices of praise, unto the house of the LORD.
But if ye will not hearken unto me to hallow the sabbath day, and not to bear a burden, even entering in at the gates of Jerusalem on the sabbath day; then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched.
