There is only one God and His name is Jesus. The name of Jesus is above all other names because by the name of Jesus, God revealed Himself in flesh and paid the price of death for the sins of all mankind.

God is a Spirit. He is holy. He is the Holy Spirit. He is the Spirit of Christ because His Spirit is in the body of Christ. God fills believers with His Spirit, which is also called the Holy Ghost (a ghost is a spirit). God is not a person, He is Spirit. And He certainly is not two or three persons! He is One Spirit and His name is Jesus.
