Although I lean highly toward the view you hold, because in my mind if someone claims to hear from God today, it would seem to be extra biblical revelation. I also don't want to be guilty of letting experience dictate my understanding of what the Word of God says.
I do however have some questions that hopefully I will find out the answers to, if not in this life, in heaven.
One of them is directly related to what Greg said he experienced concerning God talking to him.
I have had a few friends over the years that have had similar experiences, in which I will mention one.
I had a friend who was driving over a three lane bridge; he was driving in the middle lane as it was open to the traffic going his direction. He told me that, although he was traveling all by himself he heard a voice tell him audibly to get in his other lane quick. He did so only to notice that there was a car driving in the wrong lane and if he had not listened to the voice, he would have had a head on crash.
This friend of mine is not someone I believe would make something up like that and he believes it was God that told him to do this.
I now have misgivings about this being God talking, because of reasons I gave above, but I do not doubt that my friend experienced something. As far as I know I don't think he has experienced anything like that before or after.
But that brings the question in my mind, if my friend didn't obey the voice (like Greg did), who knows what might have happened?
I also don't believe that Satan knows the future, so how would he (Satan) know that there was going to be a car in the wrong lane, just moments away?
Which brings up another question, why would Satan save the life of someone? Or in the case of Greg, why would he say those things to him?
