The sequence of events in Jerusalem in its reconstitution was temple first – Ezra came to rebuild the temple – then 13 years after him the wall was built next under Nehemiah, and then after that the population and the houses were to be reconstructed. That is very interesting: temple, wall, houses.
Today there are endless books on church growth and different methods and different ways of going about things which are not the traditional ways and the biblical ways, and the great thing is said to be church growth. But they are not worshipping as they ought to, and they are not obeying God, and they haven't properly defined and defended the faith, not only the doctrines, but the practices. So everything is a pickle, and you're trying to populate the city when there's been no attention to the details of the temple – that is, the worship – and no attention to the proper defining and defending of the faith. Even here therefore in the very order in Jerusalem, you can see the order that must always be followed: temple first, wall, and then the populating of the city.
Even among Bible believers, there is nothing like as much obedience to God as there ought to be: how the church is ordered, how we go about things, how we do things. People are making innovations and inventing their own methods all the time in these days. But to recover from spiritual decline, the first thing was the great act of obedience, the careful construction of the temple, or at least its furnishings – because it was a smaller temple than the original – in exact conformity with the details which God ordained.
