The purpose of the gift of prophecy today is not to lead or guide believers into the plan of God for their lives.
All prophecy is to be judged by two things:
1. The written Word of God.
2. The inward witness of your spirit.
The primary way that God will lead us in life and ministry is through the inward witness of our spirit. In His own choosing, God will at times use outward things such as signs, dreams, visions or prophecy to further confirm what we already have in our spirit.
The spirit of man is the candle of the Lord, searching all the inward parts of the belly. Proverbs 20:27
