9 All you beasts of the field, come to devour, all you beasts in the forest. 10 His watchmen are blind, they are all ignorant; They are all dumb dogs, they cannot bark; Sleeping, lying down, loving to slumber. (Isaiah 56:9–10, NKJV)
A watchdog that cannot bark is not a good watchdog. When the devouring beasts approach the sheep, the watchdog must be able to see the danger and bark a warning to prevent the sheep from being devoured. A blind watchman cannot successfully fulfill his job. Watchmen who do not warn of spiritual danger, are blind. This was a real problem in ancient Israel; the watchmen were blinded by ignorance, and silent in the face of danger. They loved to comfort themselves, and were not ready and watchful to warn of the spiritual dangers of idolatry and immorality. In our time, God has put watchmen on the walls of Zion (pastors, evangelists, and every Christian). God’s watchmen must be vigilant to warn of spiritual danger. When they refuse to do so, fearful of jeopardizing their personal comfort, they are like Israel’s blind watchmen. They have become “dumb dogs.” The church is exposed to spiritual dangers when her watchmen do not “bark” and warn of the enemy’s approach (1 Peter 5:8). Sound the warnings against worldliness, false teaching and spiritual complacency. Be God’s watchman; not a dumb dog.
