The document discusses the concept of standing in the gap or breach. It describes Israel as being like a city in disrepair without walls. God looked for people to stand in the gap and intercede on behalf of Israel to turn away his wrath, but found none. Those who stand in the gap should act as intercessors like Moses who stood before God to save Israel, and as ambassadors like Nehemiah who prayed for and instructed Israel. The key idea is standing where few others will in order to defend and advocate for others.
