Nehemiah 11-13…Heart change.
Having rebuilt the wall, Nehemiah recognized that a physical defense for the city would be no good without a change in the hearts of the people. So he gathered the people together to hear Ezra read the law of God and express repentance for the sins that had put them into exile in the first place. There was also a great celebration at the dedication of the wall around Jerusalem, for the Lord had been faithful to grant the people success in their important endeavor (Neh. 12:27–47).
Consistent preaching of the gospel both to ourselves and to the world around us is necessary if reformation is to endure. We need to be reminded of the gravity of our sin and the greatness of our Savior in order to live in grateful obedience to His Word. Others must realize their lack of trust in Christ, so that they might become converted and their lives transformed. There will never be a point in this life when the gospel is unnecessary.
