Hi Icefloret and Everyone

seems like this is a common question. It's tough to know when and how we should be hearing from God as people talk about hearing God speak, but seldom explain how this should sound. Hearing from God shouldn't be the same as hearing audible voices the way we do when speaking to each other. So if you do hear Him or demons as someone mentioned, in an audible way it's probably more a case of your mind turning the sound of your thoughts up a little too high.
If this is the case the best thing to do is don't panic. And if upon reading this you think you may have unintentionally developed a few bad habits when it comes to hearing God's voice, don't worry. The mind is designed to be very creative, and it learns habits - good and bad - very quickly. It's quite simple once you know how the dialogue between God and Men should sound for most followers, to reign any less healthy patterns back in until you achieve a more healthy dialogue.
Here are a few pointers to help make conversing with the Lord a little clearer:
1. When it comes to communicating with God via our minds, generally speaking the 'voice' we hear shouldn't be heard with our human ears at all. It's a voice that usually sounds like a thought. Hearing from God via our minds, mostly forms part of our 'thinking' process. It shouldn't be audibly heard outside of our heads. Knowing how a conversation with God should generally 'sound' will help you to bring any loud voices back down to a healthy level, and the conversations between you and God to a place of truth instead of one your mind might be having fun exaggerating or even creating.
2. Do demons speak to us in audible voices? No, this should not be happening. When God created the Heavens and Earth He gave the world certain rules and boundaries. There is a spiritual life and there is the physical life. We don't visibly see demons or hear them speaking to us in an audible way via our physical lives. Imagine how frightening that might be. But we do hear from demons in another way. Often via our emotions and via our thoughts. Sometimes you might think of doing something bad. That thought definitely does not originate from God. Again, these voices should not be audible. They will usually come as a thought. When the devil gives us a thought it is often disguised as our own so we might be more likely to follow the bad advice. Getting it right isn't always easy. But God gives us discernment to recognise His voice from that of the devil. And as we grow in the Lord, we get better at being sharper listeners!
I hope you'll find that helpful. And don't forget, there is a wonderful and powerful blessing that our Lord has ordained upon His children:
"For God has not given us the spirit of fear; but of power, and of love, and of a sound mind." 2 Tim 1:7. (American King James version). So explore this blessing with God and enjoy being on your way to experiencing a happier and healthier soundness of mind.
May the Lord bless you on your journey
From, God's Little Helper
