So one can consider that if they are waiting for material fulfillment of prophecy for an event that awakens the spiritual capacity of all humanity, then one may have to consider will they still be waiting like people that still wait for a Messiah?
Ezekiel 43
1 Afterward he brought me to the gate, even the gate that looketh toward the east:
2 And, behold, the glory of the God of Israel came from the way of the east: and his voice was like a noise of many waters: and the earth shined with his glory.
3 And it was according to the appearance of the vision which I saw, even according to the vision that I saw when I came to destroy the city: and the visions were like the vision that I saw by the river Chebar; and I fell upon my face.
4 And the glory of the Lord came into the house by the way of the gate whose prospect is toward the east.
Baha'u'llah translation into English is "The glory of God" or "glory of the Lord"
Bab translation into English is "Gate"
Baha'u'llah came via the Gate from the East. Elijah always comes first, in this case Elijah was the Bab, the Gate.
If we are looking for a material temple to be built of stone, then it is most likely we may miss what this passage is offering from Baha'u'llah.
"...Thus have We built the Temple with the hands of power and might, could ye but know it. This is the Temple promised unto you in the Book. Draw ye nigh unto it. This is that which profiteth you, could ye but comprehend it. Be fair, O peoples of the earth! Which is preferable, this, or a temple which is built of clay? Set your faces towards it. Thus have ye been commanded by God, the Help in Peril, the Self-Subsisting. Follow ye His bidding, and praise ye God, your Lord, for that which He hath bestowed upon you. He, verily, is the Truth. No God is there but He. He revealeth what He pleaseth, through His words “Be and it is”.
