This sermon summary discusses Nehemiah's efforts to rebuild the broken walls of Jerusalem in the 5th century BC. It provides context that Solomon's Temple was destroyed in 586 BC and the Jews were exiled to Babylon, but some later returned under Zerubbabel and Ezra. The sermon focuses on how Nehemiah, while living in Susa, received permission from the Persian King Artaxerxes to return and organize rebuilding the walls. It emphasizes that rebuilding required a shared vision, organization, delegation, all pulling their weight, and encouraging one another as they worked to rebuild the walls together.
