Read verses 8-9
Q: If they were keeping the Law again, what is implied about the work beginning in the second month of the year?
A: They would have celebrated Passover and the Feast of Unleavened Bread.
Q: What does the initial step of laying the foundation most likely represent in a greater, spiritual sense?
A: Spiritually it is being established not just in the Person of Christ but in His teachings.
Therefore thus says the Lord God,
“Behold, I am laying in Zion a stone, a tested stone,
A costly cornerstone for the foundation, firmly placed
He who believes in it will not be disturbed.
— Isaiah 28:16
“Everyone who comes to Me and hears My words and acts on them, I will show you whom he is like: he is like a man building a house, who dug deep and laid a foundation on the rock; and when a flood occurred, the torrent burst against that house and could not shake it, because it had been well built. But the one who has heard and has not acted accordingly, is like a man who built a house on the ground without any foundation; and the torrent burst against it and immediately it collapsed, and the ruin of that house was great.”
— Luke 6:47-49
So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, in whom the whole building, being fitted together, is growing into a holy temple in the Lord, in whom you also are being built together into a dwelling of God in the Spirit.
— Ephesians 2:19-22
Application: True spiritual revivals and approaches to ministry are characterized as first and foremost establishing Christ and His Word in order to build something that truly lasts.
