Why do you believe in God the Mother ?? - World Mission Society Church of God

Why does Church of God believe in God the Mother, not only God the Father?

 Let's think about the reason to believe in God the Father... That is Bible testifes God the Father is needed to those who want to be saved. Thus, many people believe Jesus as a savior without any doubt.
 Likewise, How will you do if you find out also God the Mother in Bible? If God the Mother was testifed in Bible exactly, You should believe her.
But, people making many contradictions because of their stubbornness. Even though they believe in God the Father, They deny God the Mother who was proven by Bible.  It is very strange??? isn't it?
