Not in my experience.
Our capacity to hear can be influenced by many things--our practicing DOING what we've heard previouisly, for example
--our preoccupation with whatever's going on in our lives at the moment.
--our level of insecurity in general at that moment.
--the level of chatter from our own minds/spirits/hearts--the level and nature of our own self-talk.
--any crisis in our lives or even intense joy or other intense life experience at the time that has captured a lot of our focus.
--our prayer life and Bible reading life.
--our worship habits recently.
There are probably a list of others besides.
If the most powerful Being in the universe has chosen to give you a message to give to others, and you can prevent Him from giving it to you, then it seems to me that you are more powerful than He is.
Nowhere in the Bible are we given examples of the prophets of God saying, "I think God is telling me "so & so". When they spoke for God there was no subjective "feeling" or "impressions" that God was trying to get through to them. When the prophets of God spoke for Him in the Old Testament they put their lives on the line. There was no wiggle room to get out from under their "Thus saith the Lord" if it turned out that God had not spoken to them after all.
Christians (as well as others) today often take the thoughts in their own minds and attribute them to God. They often talk about a "small still voice". However, if one actually pays attention to the context of the one passage in the entire Bible where that particular phrase is used one will note that it wasn't a "small, still impression", or a "small, still nudge", or a "small, still thought". It was a small still "VOICE". Elijah actually heard a voice. And Elijah had no problem knowing exactly what God wanted him to do or say (unlike Pat Robertson who is not quite sure that he heard God Almighty accurately but is telling us his "impressions" anyway!)
Sure, on a personal level we can let sin and the distractions of life affect our relationship with God. But again, if God intends for you to hear Him, He will accomplish that goal. (Paul, on the road to Damascus, is a prime example. His heart wasn't exactly "tuned in" to the right frequency to hear from Jesus in the first place. But God was able to overcome that inconvenience to get through to him.)
Pat Robertson has accomplished a lot of good in the world, especially with his many charitable works. But I am afraid that he brings shame on the Christian community when he so often claims to personally know the Creator's mind and plans on matters not discussed in the Bible.
