Holy Ghost in Christianity

In Christianity, the Holy Ghost (or Holy Spirit) is believed to be God's presence active in the world and within believers. It serves as a guide, comforter, and source of spiritual strength, helping people understand God's teachings, grow in faith, and live rightly. The Holy Spirit is part of the Holy Trinity, which includes God the Father and Jesus Christ. Many Christians experience the Holy Spirit as a personal presence that empowers them to love, serve others, and become more like Christ.
