Nehemiah is a book about a leader who faced criticism and opposition as he rebuilt the walls of Jerusalem for its protection. The Jews were allowed to return to thier land and rebuild after time spent in exile. When these walls were built the enemy was silenced. It rendered his activities useless.
Nehemiah challenged the people to rebuild so that they would no longer be a reproach or source of shame. God showed Nehemiah the plan which allowed the people to continue to build while also guarding the attacks of the enemy. Nehemiah emphasized it was not just his idea to rebuild the city. Rather the idea had come to him from the Lord.
Do you have walls that need rebuilt in your life or the life of someone you love? God is able and is patiently waiting for us to turn to Him. He is no respector of people and what He has done before He can do again.
