The Bible testifies about God the Mother from Genesis to Revelation.

God also let us know the existence of God the Mother through the living creatures created by God. Life is given by mothers. In the same way, our spiritual life is given to us by our spiritual Mother or God the Mother.

Many people think that there is only God the Father. But the word "Father" is a title used within a family. The word "Father" implies that there are children. And children cannot exist without Mother. If there is God the Father, it's very natural that there is God the Mother.

However, many people reject to accept God the Mother even if the Bible testifies to Her. Why? It's because they do not keep the New Covenant.

[Jeremiah 31:31-34] “The days are coming,” declares the Lord, “when I will make a new covenant with the people of Israel and with the people of Judah... “This is the covenant I will make with the people of Israel after that time,” declares the Lord. “I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people. No longer will they teach their neighbor, or say to one another, ‘Know the Lord,’ because they will all know me, from the least of them to the greatest,” declares the Lord. “For I will forgive their wickedness and will remember their sins no more.”

Those who keep the New Covenant will know God from the least of them to the greatest. 

Jesus established the Passover of the New Covenant 2,000 years ago according to the prophecy of the Bible (Matthew 26:17-28; Luke 22:20.) 

Today, only the members of the World Mission Society Church of God (WMSCOG) observe the New Covenant Passover. Also, the Church of God members believe in God the Mother as well as God the Father based on the Bible.
