I'm doing everything I can to listen for that whisper...

Doing a scan of Twitter of the liberal women you will find a plethora of references to listening to the Holy Spirit's whisper. And of course these liberal ladies have all sorts of advice on how to catch that breeze whisper so that you can hear it and obey it. This lady says we have to be still to hear it.

Oh, no! I might miss it!

Ann Voskamp is kind of gross about the whisper madness.

Just...ew. That gal got some fetishes for sure.

Beth Moore says,

So Jesus tells us 'now'. Now what, I'm not sure. But we must stay close because He might say it. And according to Moore, it's better if He only has to whisper.

Lysa TerKeurst gives advice on how to make prayers powerful,

Listening for the slightest whisper ... sounds ... fleeting. I'll just take my Bible, thank you. It's solid.

So, IS the Holy Spirit whispering to us? Must we sit, or be still, or listen hard, or stay close, or press scars, or DO any other particular thing in order to receive this revelation all the other women seem to be receiving?

No.

First, the Spirit is not whispering to you. Ladies, you can relax from worry that you're not doing something particular to tune in to the frequency that you fear you're missing. There is no frequency that only a select few know and has to be tuned in just right. Remember those finicky rabbit ears before cable? With tin foil on the tips for that extra boost? It's not like that. The reason the Spirit is not whispering things to you is that the revelation from Jesus Christ about Jesus Christ is complete.

What does it mean that the revelation of God is completed in Christ according to Hebrews 1:1–2?Regarding the revelation we received in Jesus Christ (Hebrews 1:1), Dr. Lawson said there is nothing left to be said. Could you please expand on this and comment on the revelation the authors of the New Testament received from the Holy Spirit and the necessity of writing the epistles? 

Hebrews 1:1–2 looks at the big picture of God’s revelation throughout human history. Just as the Old Testament looked forward to the coming of Jesus Christ, the New Testament is the revelation of Him. This is what the author of Hebrews meant in the opening verses of that book. He was gathering up the new revelation that had been given through the apostles and their associates and referred to it as that which God “has spoken to us in His Son” (Hebrews 1:2). 

In his commentary on Hebrews, John MacArthur writes this helpful explanation:
We must, of course, clearly understand that the Old Testament was not in any way erroneous. But there was in it a development, of spiritual light and of moral standards, until God’s truth was refined and finalized in the New Testament. The distinction is not in the validity of the revelation—its rightness or wrongness—but in the completeness of it and the time of it. Just as children are first taught letters, then words, and then sentences, so God gave His revelation. It began with the "picture book" of types and ceremonies and prophecies and progressed to final completion in Jesus Christ and His New Testament (p. 5). 

The New Testament revelation given through the apostles was the fulfillment of the Lord Jesus’ promise to His disciples recorded in John 16:13–15: “But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. He will glorify Me, for He will take of Mine and will disclose it to you. All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.” 

Thus, when Dr. Lawson commented that there is nothing left to be said, he referred to the fact that no further revelation will be added to the Bible (cf. Revelation 22:18–19). For further study on this point, please listen to John’s introduction to Hebrews and his two-part series from Revelation 22:13–21.
