If you are saved the Holy Spirit is living in, and actively working in your spirit-man. The Holy Spirit does not live in or work through your mind, He is a Spirit and works through your human spirit. As such, your spirit-man knows things your natural intellect does not. Your human spirit will hear direction from the Holy Spirit and try to communicate that information to your natural understanding.
Developing a strong human spirit means learning how to identify and listen to the inner witness. This inner witness is always making an effort to connect with your natural understanding. The voice of the Holy Spirit, speaks to your spirit and guides you in every area of your life, helping to keep you safe. It is only by learning how to identify and follow this voice that you will live a prosperous and victorious life.
