The prophet Haggai encouraged the Israelites to rebuild the Temple in Jerusalem. The people that came back from captivity had begun to build but then stopped. It had been several years since they had worked on the Temple.
Haggai also gave prophecies of the church. In 2:9 we read, “The glory of this latter house shall be greater than of the former, saith the Lord of hosts: and in this place will I give peace, saith the Lord of hosts.”
Most commentators agree that this verse has reference to the church. However, what is sad is that many religious people today believe that the church is not the promised kingdom.
God established the Temple. He blessed those who built the Temple. Solomon’s Temple was considered one of the most magnificent buildings in existence before it was destroyed.
If the church has more glory than Solomon’s Temple, it cannot be because Christ failed to establish the kingdom and instead gave us the church. That would make the church a secondary institution that began from failure rather than from glory. The church is a glorious body. It has more glory than the Temple could ever have. The church is the kingdom (Colossians1:13; 1 Thessalonians 1:12). It is the heavenly Jerusalem (Hebrews 12:22).
