Nehemiah set out to build the wall around Jerusalem. He had just finished rallying the Jewish nation when the surrounding countries interjected their opinion: “are you crazy?” And “this will never work!” 

Nehemiah looked them in the eye and stood on God’s promise. “It is going to work and you have no part in it. We aren’t consulting you.”
And then Nehemiah and the people began to work on what the Lord had given them. 
Remember this: we don’t need the world’s nod of approval before we do the work of the Lord. We need only God’s confirmation.
