I agree that you need to know you're "hearing" God. His sheep know His voice, right?
That can take many forms. Trust something which PROFOUNDLY strikes you as probably a gift of the Spirit. Speak with a minister/elder to whom you're accountable and get their counsel. Make sure you are in obedience to the authority under which God has placed you even if you disagree -- remember the great lesson of David hiding out in the caves rather than rising up against the admittedly maddened annointed of God.
If you're new to hearing God, just pray for it. That's what I did. I kept praying and praying, "God, let me hear you."
the very first thing I ever "got" from Him after that was the Spirit telling me that if I heard Him, I had to obey Him. Then He started me off on little things which seemed absolutely silly, but they were safe: a sudden command to stand up or sit down or whatever, just testing to see if I would obey. That soon led me to acts in which His voice was corroborated -- he would tell me something very specific to do, and then, as I obeyed, He would corroborate it with the physical world. (For instance: He would tell me to take a bag of groceries to such and such a spot and I would find a homeless man in a captain's cap. I did, and the guy was there, and I'd never met him or been in that part of town. Another time, He told me to take a scone to a certain co-worker. I did, and it turned out that she had skipped breakfast and couldn't get away -- kind of dangerous, a it turned out, since she is a diabetic.)
Anyway, my point is: pray to hear God, and He'll teach you the way that you needto learn. Just match everything against Scripture, and learn how to test the spirits, so it's nothing evil influencing you. We've got various voices in our heads at times -- our own, Satan doing a darned good imitation of God, and then under all that, there's God. Keep working at it, and you'll learn to separate the wheat from the chaff.
But, again, I have to say (because it's a HUGE conviction of mine, I suppose), BE OBEDIENT TO THOSE IN AUTHORITY OVER YOU. Kind of like in a spousal situation -- I believe God will honor defering His immediate will in order to be in obedience and rightly, sacrificially loving someone more than He does when we just say, "Well, God told me this, so I'm rebelling against you!" He has all the time in the world for His plans to be carried out, and he knows that if we're loving someone for His sake that we are loving Him as well.
