I don't believe God has a gender. It goes to reason that God, in Himself, contains both masculine and feminine natures but that doesn't mean gender. I believe that God is incorporeal and the closest I can come to explaining that is that God is every extant attribute of reality.
Ann Barnhardt said, "If God possessed no feminine nature, then that would mean that women contained a nature that was completely outside of God. How could God create something which He Himself did not contain? Well, you might say, God doesn’t have an evil nature, but evil exists. No. Evil is merely the absence of good. Evil is not extant, just as cold is the mere absence of heat, and darkness is the mere absence of light. Femininity is an extant nature. Femininity is NOT the absence of masculinity. Femininity is an existential reality unto itself, and therefore God contains it in Himself."
