John Nelson Darby emphasizes the significance of Jerusalem as the center of worship and government, asserting that the Jewish people will be the royal nation under Christ's dominion. He explains that the restoration of Israel is prophesied and will occur in the future, contrasting their current state with the blessings promised under the new covenant. Darby highlights that while the church enjoys heavenly blessings, Israel's restoration will fulfill God's promises made to them. He cites various prophetic scriptures to illustrate the certainty of Israel's future glory and the role of Jerusalem in God's divine government. Ultimately, he underscores the importance of understanding these prophecies to avoid misapplying them to the church.
