When certain Christians speak of the Spirit’s witness (usually citing Romans 8), this sort of understanding of the expression is fairly common:
“God’s primary method of leading us in matters the Bible does not specifically address (such as which job to take or which person to marry), is the inner witness, which is a knowing communicated by the Holy Spirit to our spirit. It is not a voice, but an inner knowing.”
I am left with the obvious question: how is an “inner knowing” any more reliable or less subjective than hearing voices in my head? Is this really what the New Testament writers mean by the Spirit “witnessing”?
