Here is a excerpt from George Fox's journals about hearing the voice of God, truly those that "hear" God's voice are His!
"When I had cleared my conscience towards them, I went up to Swarthmore again, whither came four or five of the priests. Coming to discourse, I asked them whether any one of them could say he had ever had the word of the Lord to go and speak to such or such a people. None of them durst say he had; but one of them burst out into a passion and said that he could speak his experiences as well as I.
I told him experience was one thing; but to receive and go with a message, and to have a Word from the Lord, as the prophets and apostles had had and done, and as I had done to them, this was another thing. And therefore I put it to them again, "Can any of you say you have ever had a command or word from the Lord immediately at any time?" but none of them could say so.
Then I told them that the false prophets, the false apostles, and the antichrists, could use the words of the true prophets, the true apostles, and of Christ, and would speak of other men's experiences, though they themselves never knew or heard the voice of God or Christ; and that such as they might obtain the good words and experiences of others. This puzzled them much, and laid them open.
At another time, when I was discoursing with several priests at Judge Fell's house, and he was by, I asked them the same question, -- whether any of them had ever heard the voice of God or Christ, to bid him go to such and such a people, to declare His word or message unto them. Any one, I told them, that could but read, might declare the experiences of the prophets and apostles, which were recorded in the Scriptures. Thereupon Thomas Taylor,[81] an ancient priest, did ingenuously confess before Judge Fell that he had never heard the voice of God, nor of Christ, to send him to any people; but that he spoke his experiences, and the experiences of the saints in former ages, and that he preached. This very much confirmed Judge Fell in the persuasion he had that the priests were wrong; for he had thought formerly, as the generality of people then did, that they were sent from God."
