Who is the Holy Ghost in Christianity, and what does He represent?

The Holy Ghost, also known as the Shekinah, is the glory of Father God that surrounds both Him and Jesus Christ. The Holy Ghost is also a comforter, offering peace and support to those who are suffering, lonely, or in need. Even if we aren’t aware of it, the comforter is often the reason many of us keep going, guiding us when we feel lost and helping things fall into place. The truth of the Holy Ghost is that He is one with Father God and Jesus Christ. In short, the Shekinah is the radiant glory of Father God and Jesus Christ.
