In former days, cities relied on strong exterior walls to safeguard their people and wealth, serving as barriers to keep danger and enemies at bay. Similarly, as spiritual Jews building God's spiritual Temple, we must be concerned with erecting a spiritual wall to protect against the influences of the world. Just as Nehemiah reacted with alarm to Jerusalem's nonexistent walls, realizing the infiltration of pagan practices and worldliness among the Jews, we too must recognize when our spiritual wall is down, allowing harmful influences to seep in. God has assigned us the vital task of building this spiritual wall, both for the group and individually around our homes. Like Nehemiah, who faced resistance and discouragement during the rebuilding of Jerusalem's wall, we encounter challenges and must remain vigilant. We strengthen this wall by encouraging high standards among one another, showing respect for Sabbath services, redirecting negative conversations, and sounding the alarm when a brother strays outside the protective barrier. Fervent intercessory prayer is a powerful tool in erecting this spiritual wall, as Jesus Himself prayed for Peter and for us, demonstrating its importance. We must pray for protection from Satan's attacks, which can manifest as distractions, temptations, or even seemingly good things like prosperity that turn us from God. As a group, we nurture and protect each other through encouragement, prayer, and acts of love, ensuring the wall remains strong against Satan's influence. Beyond the group, our homes must be bastions against the ways of the world, sanctuaries where God is honored and Satan's thoughts and teachings are kept out. We must guard against electronic Trojan horses like television, music, and the Internet, which can breach our defenses with content that dishonors God. By maintaining vigilance and ensuring only what brings glory to the King enters our homes, we create a safe haven where our families feel secure, knowing that God's standards of love and kindness rule. Like Nehemiah, who surveyed the destruction and worked to rebuild Jerusalem's wall, we must assess the state of our spiritual wall in the church, our homes, and our lives. Rebuilding starts with restoring our relationship with our great God, a task that is vitally necessary and our responsibility right now.
