In the world of technology there is a new development called Hyper Sonic Sound (HSS). The inventor, Elwood “Woody” Norris, has engineered sound waves to travel like a laser beam for about 150 yards. This allows sounds to be heard by a person in a particular place but not by those immediately around them. You could be listening to music or specific instructions while those standing next to you would be left in total silence. If you move out of the tightly formed path of these unique sound waves you too will be unaware of any noise.
God's communication with us is very similar to these sound waves. We must be in the right place to hear the Holy Spirit, and when we’re there the message is clear. If we move away from the pathway of His voice we become unaware of the fact that He is communicating with us and we consequently miss the message.
