This is clearly the language of faith. Rebuilding Jerusalem’s walls would, under the Lord’s blessing, take away Israel’s reproach among the nations and so return honour to the God whose reputation had suffered due to Israel’s sins (Ezekiel 36:16–21). This can only be good.
18 And I told them of the hand of my God that had been upon me for good, and also of the words that the king had spoken to me. And they said, “Let us rise up and build.” So they strengthened their hands for the good work.
