Heaven" and "heavens" are used many times in the Bible, with a couple of variations of meaning. Sometimes it is relatively literal, including times when the Lord is identified with it (“Our Father, who art in the heavens,” for instance), meaning heaven as the eternal home for people who chose to do what is good in this life and let the Lord lead them to a love of being good. In other references, particularly when it is paired with “earth” or other lesser ideas (“In the beginning God created the heavens and the earth,” for instance), “heaven” or “heavens” means our internal life as opposed to our external life. In a way, these two meanings are really the same. If you think about the importance of your deepest thoughts and feelings, you can see that they are the “real” you, much more so than your body is. The relationship between the spiritual world and the natural world is similar; the spiritual world is the “real” one, and controls the natural world the same way our thoughts and feeling control our actions. So in both cases, “heaven” describes a deeper reality that we will enter fully after we die.

8328. 'The place for You to dwell in' means where the Lord is. This is clear from the meaning of 'the place' as a state, dealt with just above in 8325, at this point a state of good originating in the Divine since it is used to mean heaven; and from the meaning of 'Jehovah's dwelling-place' or 'for You to dwell in' as where the Lord is. For 'dwelling in' has reference to good, see 2712, 3613; 'Jehovah's dwelling-place' means good and consequently heaven, 8269, 8309; and 'Jehovah' in the Word means the Lord, see above in 8261. The Lord refers many times to 'the Father who is in the heavens', and when He does so the Divine within heaven is meant, and so the good from which heaven exists. Considered by Himself the Divine is above the heavens; but the Divine within the heavens is the Good present within the Truth that emanates from the Divine. This is what 'Father in the heavens' is used to mean, in Matthew,

... so that you may be sons of the Father who is in the heavens.... so that you may be perfect, as your Father who is in the heavens is perfect. Matthew 5:44, 48; 6:1.

Our Father who is in the heavens, may Your name be kept holy. Matthew 6:9. ... he who does the will of the Father who is in the heavens. Matthew 7:21.

And in addition, Matthew 10:32-33; 16:17; 18:10, 14, 19.

[2] The Divine within the heavens is Good within Divine Truth which emanates from the Lord; but the Divine above the heavens is Divine Good itself. 'The place for You to dwell in' means heaven where Divine Truth emanating from the Lord resides; for this Truth composes heaven and is meant by 'Father in the heavens', and it exists there as the good which constitutes the life of those who are in heaven. Light may be shed on this, on how Divine Truth which emanates from the Lord becomes good in heaven, by comparison with the sun and the light radiating from it. Inwardly the sun is fire, but the radiation from the sun is light. This light holds within itself heat which causes gardens to grow and become paradise-like. The actual fire of the sun does not pass over to the planet, for it would scorch and burn everything up; rather, light in which heat is present flows from the fire of the sun. In the spiritual sense that light is Divine Truth, its heat is the good within Truth springing from Divine Good, and the paradise it produces is heaven.
