If you are of the belief that God has created humankind in His likeness, that would be an admission that He is responsible for homosexuality given the evidence available. The rality is that homosexuality has exsisted throughout recorded history and beyond as a part of every race, society and culture that has been known to exsist. Either you are claiming it as the world's most widespread and longest lasting "fad" or you're just going to have to wake up to the reality that homosexuality, just like heterosexuality and bisexualty has always been a part of "God's Plan".
Homosexuality... As a christian, I am opposed to the notion that God made and accepts the behavior of the gay and lesbian agenda. First, the issue of being "born that way" was derived from 3 scientists who were gay. After mapping out the Humane Genome Project in 03, they have concluded there is no gay gene. I don't understand why we excuse a behavioral pattern of homosexuality? We definitely don't excuse murders and petifiles. We don't look for petifilia genes.
Second, God has designed us to his likeness. A gay couple can't reproduce. The parts don't line up. Its not God's design to have two of the same sex. In addition to the gay gene theory, how can it reproduce itself to the next generation. If there was, eventually it would be extinct.
In conclusion, as a christian I don't support that lifestyle. I don't condemn, that God's job.
