PSALM 19: 1-6. (NRSCVE)

1 The "heavens" are telling the glory of God; and the "firmament [skies]" proclaims his handiwork ["name"].  2 Day to day pours forth speech, and night to night declares knowledge.  3 There is no speech, nor are there words;  their voice is not heard;   4 yet their voice [b] goes out through all the earth, and their words to the end of the world. In the heavens[c] he has set a tent for the Sun 5 which comes out like a bridegroom from his wedding canopy, and like a strong man runs its course with joy. 6 Its rising is from the end of the heavens, and its circuit to the end of them;  and nothing is hid from its heat  (New Revised Standard Version Catholic Edition, Psalm 19: 1-6)

    Jesus said, "It is the Spirit who gives life; the flesh profits nothing. The words that I have spoken to you are spirit and life" (John 6:63). If you interpret scripture purely literally, you might end up as a weather forecaster or a mere admirer of NASA. However, if you view these passages as spiritual words or prophetic lyrics, you need the Holy Spirit to unfold them to you. Even when we know their spiritual meanings, our intellects may still be tempted to search for prophesied literal "signs." Merely understanding a prophecy in part brings us no satisfaction, as our inability to discern these signs leaves us unsatisfied. Yet, if we understand neither the literal nor the spiritual meanings, we will miss the clues pointing to His Second Coming.

    We need the Father of all spirits to teach us His Word. Jesus said, "But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you everything, and remind you of all that I have said to you" (John 14:26). If we can hear the Spirit, we can "hear" and "see" the Spirit within the "firmament" and the "heavens." It is this Spirit of the firmament and heavens that declares His glory and proclaims His handiwork—His name and His mission.

    Seeing the sun in a spiritual vision, for example, conveys a completely different message than staring at the literal sun in the sky. The literal skies and heavens provide hints for predicting weather—whether cosmic space weather or atmospheric conditions on Earth. In contrast, the "heavens" and "skies" we perceive in spiritual visions or scripture reveal the true handiwork and divine mission of His hands.

    The atmospheric conditions and luminaries of the sky allow us to predict natural weather, but the spiritual scriptures concerning the heavens enable us to discern God's divine handiwork across the past, present, and future. The passage in Matthew 24:29, therefore, reveals the 'spirit realms' of the heavens and the firmament: the firmament portends the work of Judgment, and His name is the Judge who judges with equity. Likewise, Zechariah 14:5–7, Psalm 50:4, 6, Revelation 6:12–13, and Genesis 8:21–22 all reveal these same divine missions.
