Romans 8:9,14 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of His. . . . For as many as are led by the Spirit of God, they are the sons of God.
As children of God, the Holy Spirit is a voice inside of us, leading us. He gives us peace or withholds peace---He tells us to go or to stay. He usually speaks through our thoughts. The Holy Spirit is a person, a presence of the Holy Trinity---God the Father, God the Son, and God the Holy Spirit. He connects us with God.
The voice of the Holy Spirit is loyal to the Word of God, characterized by its fruit of love, joy, peace, long-suffering, gentleness, goodness, faith, meekness, and temperance. The Holy Spirit is consistent with the character of Christ---his spirit of love, humility, meekness, service, obedience, submission and forgiveness. Are you seeking Him? Is He nudging you?
