Nehemiah had the massive task of rebuilding the walls of Jerusalem when the people had returned after their captivity in Babylon. It was no easy task! They were confronted by their enemies who did not want to see the walls rebuilt after being in ruins for seventy years. In one hand they carried the materials for repairing the wall and in the other they held their weapons ready for any armed attack. They built but they were constantly on guard against the enemy. Christians must do likewise for they too are constantly in a battle against the enemy.
