As I've had more time to think and pray about this, I have more thoughts on it.

I see the biggest issue on this topic is that some say if God speaks audibly, then that means it's new revelation. Here is how I see it.

At one point, my daughter did not know the world was round. She looks out at it in her experience and assumes it's flat. So as she was growing and I was teaching her, I told her the world was round, and this was new to her. However, it was not a "new revelation" as it is common knowledge at this point.

That is how I see it. Nothing that was said to me was new revelation. It's things we already know. God calls people to salvation, He calls people to preach, and He wants us to focus only on Him. So by Him saying it audibly ( in my head, not out loud where everyone could hear ), it was not new revelation.

For those that don't agree, let me ask you this. How did your preachers get their calling? What about answered prayer? Sometimes we pray about things that aren't in scripture, so how does He guide us?

Joh 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
Joh 5:25 "Truly, truly, I say to you, an hour is coming, and is now here, when the dead will hear the voice of the Son of God, and those who hear will live.

Joh 10:2 But he who enters by the door is the shepherd of the sheep.
Joh 10:3 To him the gatekeeper opens. The sheep hear his voice, and he calls his own sheep by name and leads them out.

Joh 10:27 My sheep hear my voice, and I know them, and they follow me.

Act 22:14 And he said, 'The God of our fathers appointed you to know his will, to see the Righteous One and to hear a voice from his mouth;

Heb 3:7 Therefore, as the Holy Spirit says, "Today, if you hear his voice,
Heb 3:8 do not harden your hearts as in the rebellion, on the day of testing in the wilderness,
Heb 3:9 where your fathers put me to the test and saw my works

Heb 3:15 As it is said, "Today, if you hear his voice, do not harden your hearts as in the rebellion."

And the most compelling of all, since it is yet to be fulfilled prophecy, or ongoing fulfillment depending on your stance...

Rev 3:20 Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me.

Non-reformers use this to say we have to let Him in to be saved. However, this is not the heart he's talking about, nor is it written to unbelievers.. It's an actual door to the church. This is to believers in regard to fellowship with God. We hear his voice, and open the door. If you are not hearing the voice of God, you are not fellowshipping with Him as you should be.

I've always thought God spoke in a whisper to us. He has to.

1Ki 19:12 After the earthquake there was a fire---but the LORD was not in the fire. And after the fire there was the soft whisper of a voice.
1Ki 19:13 When Elijah heard it, he covered his face with his cloak and went out and stood at the entrance of the cave. A voice said to him, "Elijah, what are you doing here?"

Job 26:14 Behold, these are but the outskirts of his ways, and how small a whisper do we hear of him! But the thunder of his power who can understand?"

We can't understand His full power if He doesn't.

Now we know that if someone whispers, you have to be close to them to hear. The further from Him we are in our walk, the harder He is to hear.
