Just a thought, but do you think that maybe Jesus came to the earth as a male because in His time, men dominated over women completely? It's just a thought - I'm not pushing right and wrong. And another thought. If Jesus had come to our earth if we had a matriarchal society (led by women - sorry if my spelling sucks), would it be possible that He might have come as a woman? It might've been just what those people related to. :)We have seen that priests must be the same gender as Christ, who is the model for all priests, due to the fact that he is the perfect mediator between God and humans. Therefore, if Christ had been born female, it logically follows that the priesthood would be all female.
The question raised today is about the power of God. God is omnipotent, which means that he can do all possible things. People debate over whether or not God can do impossible things, such as create a donkey that is also a human. "Changing the past" is sometimes listed as an impossible thing, because you can change the past to create a contradiction.
It is possible that Jesus' birth could have occurred differently. Jesus could have been born in a different place, in a different time, or to a different mother. Indeed, some people believe it would have been better if Jesus had been born under different circumstances. There are many reasons why Jesus was born in the specific way he was. One of these reasons is that God wished to act "in accordance with the Scriptures", which foretold that the Son of Man would be born from David's line, in the city of Bethlehem.
Things become tricky, when you try to explain why God/Jesus did one thing, instead of another. It is best to say that God acts fittingly in all things, although alternative actions exist.
