In the beginning God made man male and female.
"But from the beginning of the creation, God ‘made them male and female'".
But, in regards to sons of God, being male nor female bear any weight.
"For you are all sons of God through faith in Christ Jesus. 27 For as many of you as were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. 29 And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise."
A "son of God" is neither male or female.
I believe timing is an issue here.
There always seems to be an assault by the enemy upon what God is doing in the earth. The enemy has made the issue about male and female, yet God would have us approach Him in sameness, as sons, not in equality.
Perhaps we can expect a greater oneness in Christ among the saints.
