If you study languages, or have taken a class in high school, one of the things that the English language does not have is the idea of masculine and feminine words. In Spanish, the word 'friend' can be said amigo or amiga. Amigo means a friend that is a male. Amiga is for a female.
We Are All Created in the Image of God
It is said that "The Lord is fully male and fully female". It sounds complicated, but the creation story in Genesis says that, we are all created in the image of God who is both male and female. If women were also created in the image of God, then that means God is such a complete being that 'He' holds all the characteristics of both men and women.
Amigos represent male and female just as the 'He' in reference to God encompasses all of that God is. Human language is not complex enough to properly reflect the essence of God, and saying that God is 'He' is simply to tell us that he is both male and female.
What about Jesus, wasn't he a man?
It is true that manifestation of God in human flesh ― Jesus ― was in fact a man. There is no hard evidence to prove the reasons why the Lord chose to represent himself in that way, but 'He' did. One can only speculate, but it could be because man was created first. Jesus is said to be the 'Second Adam', or the beginning of a new birth for humanity.
Since it was a male that initially began the human race with the help of Eve, it only makes sense to begin again with a man. Mary was chosen to assist God is his birth into humanity, so how can you say that God doesn't love women and want them to be in his plans just as much as men?
It was not God's intention to get back at human beings for not listening to what 'He' said, the whole idea was for us to avoid the pain of the consequences by trusting 'Him' and listening to 'Him' in the first place. All humans alike live in the world with the choice to do wrong and sometimes, we take that choice, no matter how good you are.
It is not necessary to look at it as an eternal punishment, but a reminder that none of us are perfect. Men and women are different, whether you admit it or not, and have different consequences to deal. We are equal, and God sees us as equal. We are different to some degree, and that doesn't make women inferior. God's intention was never to put women down.
You have to read about the women in the entire Bible before you can conclude that it has a gender bias. You can read, 'Every Woman in the Bible: Everything in the Bible Series' by the Richards. They cite and discuss every she, her, woman, women, wife, and female name that is mentioned.
God loves us all the same whether men and women, young and old. One should not discredit the truth of the Bible for want of women to be equal. Women are equal from God's perspective, and you'll see it if you really look for it in 'His' word.
