Now, let’s overview some of the current research regarding homosexuality. Please note! The following discussion is not a conversation or argument regarding morality and values. However, we can learn some simple facts as we overview some of the genetic, anatomical, hormonal, and chemical findings regarding homosexuality:

  • The anatomy of the gay brain is slightly different from that of heterosexuals. The gay hypothalamus is about 2/3 the size of the heterosexual hypothalamus.
  • The thickness of the Corpus Callosum in homosexuals, which sends interacting signals between the left and right sides of the brain, is midway in size between heterosexual male and heterosexual female brains.
  • The tendency to be homo or hetero sexual is influenced by the amount of testosterone produced in a mother’s womb during pregnancy. The more testosterone, the more likely a male child is to be heterosexual. The less testosterone, the more likely a male child is to be gay.
  • Conversely, the more testosterone, the more likely a female child is to be homosexual. The less testosterone, the less likely the female child is to be gay.
  • Each successive male brother tends to have less birth weight than the brother born before. There is a direct correlation between low-birth weight and the propensity toward homosexuality.
  • Also interesting is the positive correlation between the sexual orientation of mom’s brothers and homosexuality. A homosexual brother on mom’s side has a positive correlation with a homosexual nephew.

That being the case, scientists have clearly determined (mostly from twin studies) that genes do not fatalistically determine our personality, brain chemistry, physical appearance or sexual preference. Our environment and personal interactions especially during our first six years and literally throughout the rest of our lives are turning genes on and off. Certain environments turn on certain genes to express themselves. The same genetic make-up (like twins raised in different environments) can cause different genes to turn on--or remain off. This is true of genes with a propensity toward homosexuality.

Hundreds of genes are now identified as contributing to a homosexual orientation and/or potential orientation. These genes are involved in a complex dance between nature (genetic material) and nurture (environmental factors). Many genes are turned on or off by contact with their environment, and, in some cases, personal choices.

I was having lunch with a Christian doctor friend who is well versed in both Christianity and the genetic, chemical and environmental issues regarding homosexuals. We were discussing the complexities of Romans One and homosexual genetics when my doctor friend said, “This means that it is time for us to get off our high horses and let God be the Judge. We need to enter this arena with love and compassion! We know we are called to do that.”

Homosexual behavior is a sin at any level. If you have homosexual leanings, God says, “Control yourself. You will never close the spiritual gap from where you are to an intimate relationship with Me while you are involved in homosexual behavior."

Similarly, heterosexual behavior outside of marriage is a sin at any level. God says, “Control yourself. You will never close the spiritual gap from where you are to an intimate relationship with Me while you are involved in heterosexual behavior outside of marriage.”

Let me share with you a few “Take Aways,” or things you might consider as you reach your own conclusions regarding this subject.
