The Good Purposes of Two Genders

Genesis 1:27 – So God created man in his own image, in the image of God he created him; male and female he created them.
I was just perusing a website that explains the differences between the 63 (and counting?!) possible genders and how a person might detect which gender he or she is.  It was a distressing exercise for me for two reasons. One, obviously there are people in this world who are hurting deeply when it comes to gender identity.  A website like this doesn’t originate in a vacuum. I feel for those people, and I want to do whatever I can to love them and encourage them.  Second, I am distressed that there are more than two genders listed as options and that “gender” is distinguished from and not synonymous with “sex.”  
When God created mankind, he had a primary and a secondary purpose for creating two sexes or genders.  The first was for companionship. Adam understood this when he saw Eve as a suitable helper, one who could tag-team with him so that together they could accomplish what God had called him to do and what he could never have accomplished on his own, i.e., have dominion over the earth. One human being could never produce the manpower needed to accomplish that gargantuan task.  He needed help from someone who could bring a different perspective and strengths.  The second purpose was so that this one-flesh relationship could produce others made in the image and likeness of God who could help them, the initial parents, do what God had called them to do and what they could never have accomplished on their own. They had to be fruitful and multiply.  Again, the earth is a very big place, and it would take a lot of image bearers to accomplish this. 
Companionship and procreation. These are the two purposes for the two sexes that God has created.  First, companionship brings the two together as one flesh. Second, that companionship is the means by which God procreates other image bearers.  Companionship in the form of a God-ordained, Christ-centered marriage should always come first.  Then procreation, in the will of God, should be the fruit of that companionship. 
While the process of enjoying that life-long companionship and the resultant rearing of those procreated image bearers takes a lot of work/humility/communication due to the differences in the personality and preferences of the man and woman who are married to each other, this is God’s plan for how companionship and procreation should be experienced. So if you are a woman, God purposefully made you one and has given you many good reasons to rejoice in that calling. Your privilege and responsibility is to flesh that out.  If God has made you a man, the same is true as well.  As the two genders learn to be and do what God has called them to be and do, then we will experience in marriage more and more of what God declared when he looked at the two of them and said, “This is very good.”
Dear Heavenly Father, thank you for your all-wise plan.  Thank you for revealing to us your purposes and through them giving your people the privilege of living purposeful lives.  Please help those who are deeply troubled and hurting because they are confused about their respective gender. Help them to learn how to rejoice in your purposes for them and give them manifold opportunities to fulfill those purposes. Draw them to yourself. And help your children to be a light to those who are in the darkness, wondering and wandering in pain and confusion, even to those who are adamantly opposed to the Gospel message.  Give us love and patience and words of hope to share even as you’ve done that for us through the person and work of your son, Jesus Christ. In whose name we pray, Amen.
