When God speaks and we recognize the voice as his voice, we do so because our familiarity with that voice enables us to recognize it. We do not recognize it because we are good at playing guessing games. One indicator that will help us identify that voice as God’s voice is content. This is a matter of what information the voice conveys to us.
The content of a word that is truly from God will always conform to and be consistent with the truths about God’s nature and kingdom that are made clear in the Bible. Any content or claim that does not conform to biblical content is not a word from God. Period! As Charles Stanley comments in How to Listen to God, “God’s Voice will never tell us to engage in any activity or relationship that is inconsistent with the Holy Scriptures.”
