Keep Up Your Spiritual Guard
The 4,000-mile-long Great Wall of China was built to keep invaders from the north. The first wall was constructed by Shi Huangdi, the first emperor of China, who lived between 259 - 210 BC. But in AD 1644 the Manchus broke through the Great Wall and overran China. They did this by bribing a general of the Ming dynasty to open the gates.
During the reconstruction of ancient Jerusalem, Nehemiah understood the acute danger posed by those who opposed the rebuilding of the city’s ruined walls. So he commanded constant vigilance. Half of the workers were to stand watch while half rebuilt the walls.
As Christians, we must be vigilant that nothing breaches our spiritual defenses. Even the most mature believer can never afford to let down his guard.
