God's voice is roaring through the works of His worshippers. In the course of work, worshippers may be faced with challenges, and as the process continues, God's voice will roar to silence the murmurings of the naysayers.
Amos 3:8 - The lion has roared. Who will not fear? The Lord the LORD has spoken. Who can but prophesy?
The example of murmur, while the Israelites were on a mission, the doubtful murmured int he wilderness.
