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.

The Lord is life itself, and we are recipients of life. This is true even of the most evil spirits, who loved only themselves in life and hate and deny the Lord from their place in the lowest hells; the Lord forces life upon them, despite their rejection, in the amount necessary to keep them from ceasing to exist. The situation is much different, of course, with people who accept and follow the Lord; by doing this they open themselves up to the inflow of life, and become more full the more open they are. This is the “life” in question when the Bible uses that word. It indicates spiritual life, the life that comes from the Lord into our hearts and minds. We accept life from the Lord by learning about Him, learning what is right and wrong, and by determining that we will stop doing what's wrong and instead do what is right.
