In former days, cities relied on strong exterior walls to shield their people and wealth from danger. These fortifications, equipped with gates and towers, controlled access and kept enemies at bay. A breached or broken-down wall spelled disaster for the inhabitants, exposing them to attack. Similarly, in the story of Nehemiah, the absence of Jerusalem's walls left the returning Jews vulnerable to the pagan influences of the surrounding world, leading to intermarriage, Sabbath neglect, and a return to the sins that had once caused their exile. Nehemiah, recognizing the peril of a broken-down wall, sought permission to rebuild it, understanding that without this protection, worldliness infiltrated their lives. Spiritually, we are tasked with building a wall to guard against the influences of satan's world. Just as a broken-down wall in ancient times allowed enemies to enter, a lack of spiritual barriers today permits harmful attitudes and temptations to creep in. We must actively construct this wall through prayer, encouragement, and upholding high standards within our community. When we see a brother straying outside the protective wall, we should sound the alarm and guide them back to safety. Fervent intercessory prayer, as exemplified by Jesus Christ praying for Peter, strengthens this wall against satan's attacks. Beyond the communal wall, we must erect a personal, spiritual wall around our homes, making them sanctuaries where God is honored and satan's ways are kept out. A broken-down wall in the home allows worldly entertainment, music, and internet content to infiltrate, undermining God's values. We must guard against these electronic Trojan horses by evaluating what we permit inside our walls, ensuring only that which brings glory to God enters. Like a schoolyard without a fence, a home without a spiritual wall leaves its inhabitants exposed and insecure. By rebuilding this wall through vigilance and a restored relationship with God, we create a safe haven where love and kindness prevail. Just as Nehemiah surveyed the destruction of Jerusalem's wall and worked to rebuild it, we must assess the breaches in our spiritual walls—within the church, our homes, and our lives—and dedicate ourselves to their restoration.
