Arcana Coelestia # 6573
6573. 'In order to do what is in accord with this day' means that this is in accord with order from eternity. This is clear from the meaning of 'doing', when used in reference to the Divine, as order (for whatever the Divine does is order); and from the meaning of 'in accord with this day' as from eternity, dealt with in 2838, 3998, 4304, 6165, 6298.
Arcana Coelestia # 4304
4304. 'Even to this day' means that, perpetually so, falsities would not be attached. This is clear from the meaning of 'even to this day', where this phrase is used in the Word, as that which is perpetual and eternal, dealt with in 2838.
