I still hold that female imagery of God is useful. God cannot be thoroughly portrayed in male terms.

Personification of Wisdom:
Proverbs 8:1-2:
"Does not wisdom call out? Does not understanding raise her voice? On the heights along the way, where the paths meet, she takes her stand..."

Proverbs 8:22-26 (& following that too):
"The LORD brought forth as the first of his works, before his deeds of old; I was appointed from eternity, from the beginning, before the world began. When there were no oceans, I was given birth, when there were no springs abounding with water; before the mountains were settled in place, before the hills, I was given birth, before he made the earth of its fields of any of the dust of the world."

These are both evident personifications of Wisdom/Sophia, & they both portray her as female. The Wisdom spoken about here is clearly not just an attribute of God; this Wisdom has been with God since before the earth was formed, and is a personification in its own right.

Wisdom 8:1:
"She reaches mightily from one end of the earth to the other, and she orders all things well."

This is pretty obviously another personification of Wisdom...

Wisdom 9:9-10:
"With thee is wisdom, who knows thy works and was present when thou didst make the world, and who understands what is pleasing in thy sight and what is right according to thy commandments. Send her forth from the holy heavens, and from the throne of thy glory send her, that she may be with me and toil, and that I may learn what is pleasing to thee."

More personification. Note that Wisdom is not just an attribute of God here, but dwells in heaven with God, and can be sent separately...Maybe this could be the Holy Spirit?

I do not think that it is right to say that God is to be spoken about as Father because that's how God is revealed to us - Alistar McGrath:
"To speak of God as Father is to say that the role of father in ancient Israel allows us insights into the nature of God, not that God is a male human being. Neither male nor female sexuality is to be attributed to God."

If male nor female sexuality are to be attributed to God, then surely, there is room for qualities from both sexes to be metaphorically applied when talking about the nature of God. In applying metaphors of both sexes, it embraces all of God's people, rather than serving to exclude them.

Throughout the Bible, the Holy Spirit is consistently female. This originates in the Old Testament writings.

Often, divine Wisdom is associated with the Holy Spirit. Wisdom is often spoken of as having been with God for all time (see above); Genesis 1:2:
"Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters."

This has strong resonances with Proverbs 8, where Wisdom is personified as having been with God in Creation, & is shown as a 'she'.

I still maintain that female imagery is valuable & applicable when talking about God. I also think that male imagery is good in talking about God too, so I don't want to dismiss that entirely - I just think that there are other ways too.
