Unlike most people you will run into on Christian message boards I am not ignorant of your dilemma. It is because of the arrogance of western civilization and the pedestal some doctors put themselves on that you were butchered as a child. Had you been born in a 3rd world country where people accept their children as they are born and allow an incompletely formed body to mature with age and let “nature” determine sex you would not have been butchered. Western culture is so sexist that some doctors think it is their duty to “fix” natures “goofs”. A simple DNA test can determine genetically the sex of a child. But doctors want to determine the sex at birth and make decisions based on appearances.
Why did God create 2 sexes? That is a complicated question. Some puritanical and overzealous fundamentalists see the only purpose of sexual intimacy as procreation. That is both illogical and denies God’s truth. If procreation were the only reason for sex then women would go into heat like most mammals, and men would go into rut at the same time. But sex has another purpose, to bond marriage partners as one and to develop social and family intimacy for the married couple. (This is an oversimplification but will have to do.) Mankind, unlike most animals, is gregarious and social and lived in extended family units.
So why do some evangelicals and Phelp’s in particular lump the intersexed with gays? I would think the main reason is that transsexuals, some intersexed, and others who identify with the gay community for political reasons came together to fight for equal rights. What was started as gay/lesbian political action groups evolved into GLBT political action groups.
Did God know Adam would fall? Yes, and before the creation of the world God designed and implemented His plan to redeem mankind. Part of that plan was to allow anomalies that include the intersexed, oversexed, birth defects, and etc. Why? I can’t really answer that question because I am not God. But, from His word I would surmise it was so we would rely on Him and His sovereignty to help us live our lives.
Arrogant men have butchered you, but you have talents that you can use to glorify God. Since you lack a sex drive (or am I assuming something) you don’t have to deal with sexual tension and are therefore free to concentrate on other aspects of being a loving and compassionate human being. Instead of being concerned with the problems associated with child rearing and other situation common to married life you are free to pursue a truly intimate relationship with your Creator that in the long run is so far above any sexual intimacy one has to experience it to understand it.
Believe me, I know from experience, sex is overrated and most if not all heterosexuals underrate celibacy. True intimacy can be ruined by sex getting in the way.
What you see as a burden can also be seen as a blessing. It is up to you.
If people would only educate themselves instead of judging based on a lack of information you would have an easier time in this life. But the reality is people are judgmental and don't take the time to learn.
