Blain, where is the scientific research, the genetic studies to show that people have a "homosexual" gene? Because you better believe the gay lobby has looked long and hard, and they haven't found it!
As far as sin, this is pretty obvious!
"But I say, walk by the Spirit, and you will not gratify the desires of the flesh.17 For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do.18 But if you are led by the Spirit, you are not under the law.19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality, 20 idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions,21 envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God." Gal. 5:16-21
I had been a Christian about 2 years when I read this passage. I was pretty please with myself, that I had not had a single drop to drink since I had been saved.
But I just about died when I saw "fits of anger" also translated "outburst of anger." I came from a family where everyone lost their temper. It had to be genetic! I had the example of my father, in particular, and his outrageous temper. It had to be environment!
At any rate, it certainly wasn't my fault. It wasn't fair it was a sin. Sure the homosexuals and other sexually immoral people were sinful, but I couldn't control my temper, even if I tried.
And tried, and tried, and tried! And 30 years later, I was still trying! But at least I knew it was a sin, and it was my fault. And repentance was something I needed to do often!
The same with homosexuals - they need to acknowledge their sin and repent of it. There are simply too many verses to say it is not sin. God's plan has always been for one man and one woman to marry and be together.
It has never been for people to live the "gay" (read: promiscuous) lifestyle. It has never been to act on impulses that are against God's will. I once went into a lesbian forum, to see what they were about. It was very interesting. The woman all told stories of being abuse, raped or even shot by men. About how much they hated men for what they had done to them. After a short while, I couldn't stand the posts, and left. But it did tell me that the lie of people being "born gay" was not right!
But I don't think we should be mean to gays, but instead love them, and help them to know Christ and escape that lifestyle.
