Arcana Coelestia # 23
23. Nothing is more common in the Word than for the word 'day' to be used to mean the particular time at which events take place, as in Isaiah,
The day of Jehovah is near. Behold, the day of Jehovah comes. I will make heaven tremble, and the earth will be shaken out of its place, on the day of My fierce anger. Its time is close at hand, and its days will not be prolonged. Isaiah 13:6, 9, 13, 22.
And in the same prophet,
Her antiquity is in the days of antiquity. On that day Tyre will be forgotten for seventy years, like the days of one king. Isaiah 23:7, 15.
Since 'day' stands for the particular time it also stands for the state associated with that particular time, as in Jeremiah, Woe to us, for the day has declined, for the shadows of evening have lengthened! Jeremiah 6:4
And in the same prophet,
If you break My covenant that is for the day and My covenant that is for the night, so that there is neither daytime nor night at their appointed time. Jeremiah 33:20, 25.
Also,
Renew our days as of old. Lamentations 5:21.

TEACHINGS ABOUT CHARITY
It has been stated above that self-love and love of the world residing with a person constitute hell. Now the nature of those loves must be stated, in order that a person may know whether he is ruled by those kinds of love, and consequently whether he has hell within himself or heaven; for a person has within himself either hell or heaven. The Lord teaches in Luke 17:21 that the kingdom of God resides within a person; therefore that is also where hell resides.
