God refers to Himself exclusively in the masculine in the Bible. However, He does use feminine traits and examples to illustrate who He is and what He is like.
This article provides some useful context and examples:

At the resurrection, believers in Christ will receive new, perfected, sinless, incorruptible bodies. These bodies will apparently be neither male nor female, and Christ describes those who are resurrected as being like the angels. However, the resurrected saints who comprise the Church are depicted as one living entity. God is One but is comprised of three persons. We (humans) individually, in our present earthly state, have a singular personhood with three parts: body, soul, and spirit. I think it is accurate to say that the Church, universal and eternal, will be One but comprised of billions of persons.
The Church is the Bride of Christ. As animals serve to represent higher-ordered beings in the Heavenly realm, and our relationship with them is similar to the relationship God has with them, so the concept of marriage is somewhat symbolic. In other words, marriage merely helps us relate to the Heavenly relationship, which is beyond the finite ability of our minds to comprehend presently.

For this is the way of wisdom -- to acquire ideas one after another until, in the end,
there emerges one complete concept for which all of the prefaces were necessary.
