The final history books of the OT, lead us to think about the hard work of building God's temple and kingdom. Clearly the old temple's glory would not be restored, but God's glory is worth our efforts because we look forward to a better temple. The book of Esther too teaches us about the limitations of man. Yet, we are responsible to do what we can, and God may use our works if he pleases. God will build a dwelling place for himself and we must look forward to that one day when people from all nations will worship the Sovereign God of earth and time together.
