The Holy Spirit
The Holy Spirit is a Person, Presence, and Voice Who connects us with God because He is God.
John 14:16,17 And I will pray the father, and he shall give you another Comforter that he may abide with you for ever; Even the Spirit of truth; Whom the world cannot receive because it seeth Him not, neither knoweth Him: but ye know Him: for He dwelleth with you and shall be in you.
Romans 8:9 . . . . Now if any man have not the Spirit of Christ, he is none of his.
The Holy Spirit leads us through our prayer life, through time in the scriptures, through teaching and preaching, through situations and experiences.
The voice of the Holy Spirit will be consistent with God's Word, His fruit--love, joy, peace, longsuffering, gentleness, goodness, faith, meekness and temperance. He always lifts up Jesus Christ, not Himself.
