The term "Holy Ghost" refers to the third person of the Holy Trinity in Christian theology, alongside God the Father and Jesus Christ. The Holy Ghost is often associated with divine presence, guidance, and inspiration, playing a crucial role in the lives of believers. In many Christian traditions, the Holy Ghost is believed to be active in the world, providing comfort and strength to individuals. In the Bible, the Holy Ghost is described as a helper or advocate, particularly in the New Testament. One significant event involving the Holy Ghost is Pentecost, when the Holy Spirit descended upon the apostles, empowering them to spread the teachings of Jesus. This event marks the beginning of the Christian Church's mission to share its message globally.
