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.

There are two aspects to the life of each person. We might call them "heart" and "mind," a part of us that wants and feels and a part of us that thinks and knows. The Writings usually refer to these as the "will" and the "understanding." They are reflections, and receptacles, of the Lord's infinite love and infinite wisdom. Of the two, the heart or will is ultimately the most important. Who we actually are is determined by what we love, and the things in our heart ultimately determine our place in heaven (or hell). But the will is beyond our control; we can't force ourselves to want something good or to not want something bad; we can control our actions, but not our feelings. Because of this power, the Lord works subtly and carefully in our hearts, in ways we can't sense. Most of the work and interaction goes on in our minds through the working of what the Writings call "Divine Truth," which is essentially the Lord's entire essence expressed in a form that is compatible with our minds. When the Bible talks about the Lord's "spirit," it represents this operation of Divine Truth in our minds, the way he reaches out and embraces us, and invites us to embrace him back. And when the Bible talks about people having "spirit," it is talking about our minds when we embrace Divine Truth.
