Often God speaks to us in a still and quiet voice. It's in the Bible, I Kings 19:11-13, NIV. "The Lord said, 'Go out and stand on the mountain in the presence of the Lord, for the Lord is about to pass by.' Then a great and powerful wind tore the mountains apart and shattered the rocks before the Lord, but the Lord was not in the wind. After the wind there was an earthquake, but the Lord was not in the earthquake. After the earthquake came a fire, but the Lord was not in the fire. And after the fire came a gentle whisper. When Elijah heard it, he pulled his cloak over his face and went out and stood at the mouth of the cave. Then a voice said to him, 'What are you doing here, Elijah?'"
Sometimes we can best recognize God's majesty when we are quiet. It's in the Bible, Psalm 46:10, TLB. "Stand silent! Know that I am God! I will be honored by every nation in the world!"
There is strength in quietness. It's in the Bible, Isaiah 30:15, NIV. "In repentance and rest is your salvation, in quietness and trust is your strength."
Righteousness produces peace and quiet confidence. It's in the Bible, Isaiah 32:17-18, NIV. "The fruit of righteousness will be peace; the effect of righteousness will be quietness and confidence forever."
Quietness is a proper expression of reverence. It's in the Bible, Habakkuk 2:20, NIV. "But the Lord is in His holy temple; let all the earth be silent before Him."
