Yes, it's possible to hear God. I did not say "only" there.Interesting point. So why can't people pray and be able to hear voices from only demons or insanity?
Someone who hears a voice should be very careful, especially if they neither feel God nor are in a state of grace during the locution. I know, however, that if the person is not a state of grace, then a good voice will direct the person to become in a state of grace(ie., the apparition to Paul was first for Paul to repent and then Paul was given instructions to preach.)Why is God left out of that equation?
While a evil voice may be able to disguise himself/herself for a while, the intention will eventually become plain.
I've seen people deceived.If you're praying and you hear a response in your prayer, why do fellow believers think you're in la la land for daring to say that God spoke to you?
Just hearing a voice in prayer does not mean the voice is God.Even if someone makes such a claim that they heard the voices in prayer and their prayer showed them that it is the word of God, why are these people seen to be mad?
