Throughout the Old Testament, God revealed glimpses of a realm beyond our sight — a spiritual world active behind the scenes of human history. From the very beginning, Scripture shows that creation is not limited to the physical; there is an immovable spiritual dimension governed by the Lord of hosts.

When Elisha and his servant were surrounded by an enemy army, fear filled the young man’s heart. But Elisha prayed, “Lord, open his eyes that he may see,” and suddenly he beheld a heavenly host — chariots of fire surrounding them (2 Kings 6:17). This moment reminds us that God’s presence and protection are real, even when unseen. The armies of heaven were not a metaphor — they were active, powerful, and present.

Likewise, Daniel saw visions of spiritual battles that shaped earthly kingdoms (Daniel 10:12–14). Angels were dispatched in response to prayer, and a spiritual prince resisted them — proof that unseen forces influence nations, decisions, and history. The Old Testament consistently reveals a world where angels minister, where the presence of God fills the temple, and where supernatural encounters shape God's covenant story.

Yet these glimpses pointed forward to something greater — a coming revelation through the Messiah who would reveal the Father fully (John 1:18). The unseen realm in the Old Testament was a foreshadowing, preparing humanity to see heavenly truth more clearly in Christ. The spiritual realities hinted at in shadows would soon be revealed in the light of the Son of God.
