The Holy Spirit is the third member of the Trinity. It is a spiritual nature, without flesh and bones. It is often called the Spirit, the Holy Ghost, the Spirit of God, the Spirit of the Lord, or the Comforter.
The Holy Ghost works in perfect communion with Heavenly Father and Jesus Christ, performing various tasks to help us live righteously and receive the blessings of the gospel.
He “bears witness of the Father and of the Son” and reveals and teaches “the truth of all things.” Only through the power of the Holy Ghost can we have a sure testimony of Heavenly Father and Jesus Christ. His communication with our spirit is far more accurate than any communication we can receive through our natural senses.
As we seek to follow the path that leads to eternal life, the Holy Spirit guides our decisions and protects us from physical and spiritual dangers.
Matthew 3:11
John 15:26
