Is the Christian god a man without a woman?

No, my God is not a man, that He should need a woman. My God is God, the creator of all mankind. My God is Love !

The Church is GOD's 'Bride' and is revealing the Female Essence of GOD through Her perfection and union with GOD:

'Let us rejoice and be glad and give the glory to Him, for the marriage of the Lamb has come and His bride has made herself ready.' (Revelation 19:7).

'Husbands, love your wives, just as Christ also loved the church and gave Himself up for her, so that He might sanctify her, having cleansed her by the washing of water with the word, that He might present to Himself the church in all her glory, having no spot or wrinkle or any such thing; but that she would be holy and blameless. So husbands ought also to love their own wives as their own bodies. He who loves his own wife loves himself; for no one ever hated his own flesh, but nourishes and cherishes it, just as Christ also does the church, because we are members of His body. FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND SHALL BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH. This mystery is great; but I am speaking with reference to Christ and the church.' (Ephesians 5:25-32).

God is the fullness of maleness and femaleness.

Gen. 1.27

In His image He made them:

male and female He made them.

We use the masculine to describe God because the English language does not have a word that describes a neutral thing as being anything but an object, as oposed to a living being.

God wants to be known as a loving Father (because fathers are more lacking in the world than mothers), but He also describes Himself as a 'mother hen' protecting her chicks, and as having the 'heart of a mother'.

The Life Force that created the galaxies isn't 'needy' as you are suggesting in your ignorance here.

God can raise children for Abraham from the stones if He wants. He doesn't 'neeeeeed' any of us.

You should read your Bible.
