Christmas reminds us the veil is thin and the other-side is near.
Jesus is bringing GOD's Kingdom, and when HIS Kingdom comes in all its fullness, GOD will blow the fog away and we'll see clearly.
1 Corinthians 13:12 - We don’t yet see things clearly; now we see through a glass, darkly. We’re squinting in a fog, peering through a mist. But it won’t be long before the weather clears and the sun shines bright! We’ll see it all then, see it all clearly.
