Who is God the Holy Spirit?
God the Holy Spirit is the third Person of the Trinity. He shows people how wonderful the Lord Jesus Christ is (John 16:14) and He helps sinners believe in the Son of God. When someone believes in the Son of God He gives him or her gifts so that they can encourage other Christians (1 Cor. 12:7). The Holy Spirit lives within every Christian and helps them become more like the Lord Jesus Christ (John 14:16-17; Rom. 8:14-17).
The Holy Spirit shows us how wonderful Jesus is
He will glorify me, for he will take what is mine and declare it to you (John 16:14)
The gives Christians Spiritual Gifts
To each is given the manifestation of the Spirit for the common good (1 Corinthians 12:7)
The Holy Spirit lives within every Christian
For all who are led by the Spirit of God are sons of God. For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him (Romans 8:14-17)
