"I will hear what God the Lord will speak: for he will speak unto his people, and to his saints" (Psalm 85:8)
I once slipped into a noonday service in New York City and I heard something I will never be able to forget.
A minister speaking that day said: "We assume that if a man has heard the Christian gospel he has been enlightened. But that is a false assumption. Just to have heard a man preach truth from the Bible does not necessarily mean that you have been enlightened."
God's voice must speak from within to bring enlightenment. It must be the Spirit of God speaking soundlessly within.
I believe that God has related these somehow: the voice of conviction in the conscience and the Holy Spirit, the point of contact, witnessing within man's being. A person has not been illuminated until that voice begins to sound within him.
Men and women need to be told that it may be fatal to silence the inner voice. It is always perilous to resist the conscience within; but it may be fatal to silence that voice, to continue to ignore that speaking voice within!
When we fail to hear His voice, it is not because He is not speaking so much as that we are not listening.
