The Bible teaches that there is one God (Deuteronomy 6:4) who is spirit (John 4:24) who cannot be seen or approached by man, for the salvation of man God manifested in human flesh (body),revealed in his union nature calling himself as Father, Son, and Holy Spirit. (Colossians 2:9) “For in Christ dwells all the fullness of the Godhead bodily”. God called himself as FATHER because he is the Creator of everything and everyone. (Isaiah 26:4 & I Corinthians 10:4) The same God called himself as SON because he is the Saviour of mankind, manifested in flesh (1 Timothy 3:16) i.e., born a man by a virgin birth and was crucified, buried and resurrected, purchased and established his church (Acts 20:28) and that he will return again for judgment when his Father determines the time for history to end. God calls all people to follow him and accept the teaching that Jesus Christ is the one mediator between God and mankind. (Matthew 28:20) The same God called himself as HOLY SPIRIT because in his Resurrected body he is in Heaven now and in his Spirit he is in earth now, he is the guiding Spirit of the Church to grow spiritually. Believers are redeemed from judgment when they accept this teaching and follow the guidelines for holy living as explained in the Bible.
