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.

454. Some spirits think that heaven and heavenly joy consist in a life of ease in which they are waited on by others. But they are told that happiness in no way consists in being inactive and finding happiness in that. This would mean that everybody wished to subordinate other people's happiness to his own, and when everybody wished to do that nobody would have it. Such life would not be an active life but a life of idleness in which they would become listless, even though they may well know that unless one is active there is no happiness in life. Angelic life consists in use, and in good deeds of charity. For angels never feel happier than when they are informing and teaching spirits that stream in from the world, or when they are ministering to men and are preventing the evil spirits with them overstepping the mark, and inspiring men with what is good; also when they are arousing the dead into the life of eternity, and after that introducing such souls into heaven if they are capable of it. The happiness they find in all this is more than can possibly be described. Angels in this way are images of the Lord; they love their neighbour more than themselves; and this is what makes heaven heaven. Consequently angelic happiness consists in use, stems from use, and is proportionate to use, that is, to the good deeds of love and charity. As for those spirits who had adopted the idea that heavenly joy consisted in being idle, and that in idleness they would be experiencing eternal joy, they were allowed - once told all this to make them ashamed of that idea - to perceive what such a life was really like. They perceived that it was an utterly dreary kind of life, and destructive of all joy; and that after a short while they would find it repulsive and nauseating.
