The Holy Spirit is understood in Christianity as the third person of the Trinity, alongside God the Father and God the Son (Jesus Christ). The Holy Spirit is not merely a force or power but a divine person with a mind, emotions, and will, fully God and co-equal with the Father and the Son
. The Holy Spirit is God's active presence in the world, involved in creation, prophecy, and guiding believers. It animates and sustains all creation, bringing life, order, and renewal, especially transforming human hearts so people can know true life and love
. In the New Testament, the Holy Spirit is closely connected to Jesus, having conceived Jesus in Mary's womb, descending on Him at His baptism, and promised to be sent to His disciples as a helper and comforter
. Christian doctrine holds that the Holy Spirit inspires believers, helps interpret Scripture, and grants spiritual gifts and fruits. The Spirit intercedes for believers, guides them to live according to God's will, and is worshiped as God
. The Holy Spirit is also described as "the Lord, the Giver of Life" in the Nicene Creed, emphasizing its divine nature and role in salvation and sanctification
. In summary, the Holy Spirit is the personal, divine presence of God active in the world and in the lives of believers, essential for spiritual life, guidance, and transformation
