Spirit
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.
Deuteronomy 8:6-10
6
You shall keep the commandments of Yahweh your God, to walk in his ways, and to fear him.
7
For Yahweh your God brings you into a good land, a land of brooks of water, of springs, and underground water flowing into valleys and hills;
8
a land of wheat and barley, and vines and fig trees and pomegranates; a land of olive trees and honey;
9
a land in which you shall eat bread without scarceness, you shall not lack anything in it; a land whose stones are iron, and out of whose hills you may dig copper.
10
You shall eat and be full, and you shall bless Yahweh your God for the good land which he has given you.
