Emmanuel Bible Church
What drove [Haggai's] relentless urging of the rebuilding of the temple was his theology of the temple, and not some sort of fanatical preoccupation with architectural grandeur.
It was [Haggai's] theology of who the Lord is that framed his call for appropriate submission to the will of the sovereign Lord for postexilic Israel. It
was [Haggai's] theology of holiness that mandated the warning that an impure people were incapable of pure worship but instead defiled everything with which they came into contact.
