John Nelson Darby explores Haggai 2:5-9, emphasizing that the prophecy speaks of a singular house of God rather than two distinct ones. He highlights God's promise to remain with His people, urging them not to fear, and asserts that the latter glory of God's house will surpass the former. Darby interprets the passage as a call to recognize the true glory that comes from God's presence, which transcends worldly power and stability. He suggests that the focus should be on the spiritual unity and glory of God's house, which will attract the nations, rather than on material wealth or external appearances.
