Thomas Brooks emphasizes the importance of being silent before the Lord and patiently waiting for Him, urging the soul to refrain from muttering, murmuring, and complaining during times of affliction. He commands the soul to find peace and stillness, recognizing that there is no justifiable reason to quarrel against God's righteous hand. Brooks encourages believers to lay their hand upon their mouth and embrace a quiet spirit, as inner turmoil can lead to accountability for our discontent.
