Your inner man is your Master Control system for communicating with God and it has a voice. Developing a strong human spirit means learning how to be sensitive to the voice of your inner man. Most of the world refers to that inner voice as being the conscience. It is that still small voice inside you that corrects you and once you are saved, the Holy Spirit is in constant communication with your inner man. The voice of your spirit will always tell you when you have violated a commandment of the Lord. You can harden your heart and refuse to listen to that voice, but it will always speak. You will be without excuse when you stand in judgment before the Father; He has given you everything you need to live a Godly life, including an inner man that is sensitive to Him.
