lamplady,
Forgive me, this thread is long and I've had a busy week so maybe I've missed something in my read through...
You seem to be struggling with the concept that gay love is wrong because the Bible condemns gay sex. So, if gay love is "real" and since love leads to sex, how can God condemn gay sex? Or, maybe, since God clearly condemns gay sex, perhaps gay love isn't real?
Hopefully, that is the gist of your query here, because it's what I'm going to address. (Now watch me be totally off! ;))
I don't think there is anything sinful about gay love, and by gay love I do mean love experienced by one gay person to another of the same sex. Just as I don't think there is necessarily anything sinful about hetero love for a person of the opposite sex that one is not married to.
I am purposely excluding from my response here the kind of love that we have for good friends, family members yadda yadda. I am speaking only of the kind of love that is the basis for marriage or long term commitments.
I can honestly say that I experienced this kind of love with three guys. One most likely would have wound up my husband except that life took us 2000 miles away from each other and the relationship didn't survive the distance. I'll call him "Tom". The other, "Harry", we were engaged for awhile, but there were issues and we broke up. The third is my beloved Steve.
For "Tom" and "Harry", my love for them was completely real. 'Smatter of fact, as much as I love Steve, I still have a very warm place in my heart for "Tom". My love for "Harry" the year we were together, was also very real. However, as has been mentioned before, sex was out of the question with either of these guys because I wasn't married to either of them. In the situation I was in with both of these guys, as well as one other guy that I was seriously attracted to, but in an unrequited way, I faced temptations that are common to all of us, straight or gay, the temptation to allow lust to enter into my heart and cause me to think impure thoughts being a biggie, but also the temptation to dream much more into the relationship that was appropriate for what we had at the time, which is also a common temptation.
You brought up a good point, the hetero at least is able to "look forward" to marriage, whereas the gay cannot. And, that is a very valid issue to address, an issue without an easy answer, especially since we really should control our thoughts and emotions about another person and not "go there" with someone we have no intention of marrying. (Easier said than done, and I won't pretend that I was successful in remaining pure in this regard.)
However, Christ-empowered gave us insight as to what God's answer can be, and this is something that can only come from God...the ability to be gay and yet, through Christ be able to form a loving relationship with someone of the opposite sex.
This was certainly the testimony of one of my gay friends who has always identified himself as a Christian first, but also gay. However, through much prayer and obedience to God, God brought a woman into his life and they are married, have been for over 20 years now and have two girls. His sexual orientation is something that he must take to the cross daily as the case may be, but nonetheless, his love for his wife is just as "real" as his love for the first guy that he was attracted to.
Another avenue that God can give homosexuals is celibacy. As someone who didn't marry for years, believe me, celibacy isn't easy, but God enabled me to be celibate, even when I was with "Tom" and "Harry", and He can enable a homosexual who is committed to obeying His commandments to be celibate as well.
During my years as a lonely celibate, I had many dreams about what married life would bring me, dreams that all my desires would be fulfilled once I was a wife and mom. Well, life just isn't like that now is it? Not that I'm complaining, I have a great marriage to a great guy, but marriage didn't fulfill all my desires.
And, this is something that the Christian who struggles with homosexuality must come to terms with as well...that it's normal to believe "if only God would allow me to be with him/her then I my happiness will be complete". Normal, but not realistic. Marriage is a struggle. While the love is real, the issues are just as real. If they weren't there wouldn't be as high a divorce rate. It would be easy for a homosexual to try to cast God as a bad guy who won't allow one's heart's desires, but it's best to keep in mind that not all of our desires are realistic or attainable in any case.
I feel for the homosexual who is committed to obey God in his/her sexuality, because once one is in love, it is really hard to remain celibate and keep the relationship. So, for a homosexual who loves another of the same sex, the situation is very tough, and most often leads to facing giving up the relationship, or falling into sin.
However, we must guard against the idea (most likely a lie of the enemy's) that God isn't aware of the special needs and issues a homosexual who is committed to Him faces. First and foremost, nobody is going to love that person more than God Himself and God, via the new life He gives all of us in Christ, can and does fulfill His promise Romans 8:28 to the gay causing all things, (even same sex sexual temptations) to work to the good of one called according to His purposes.
How He works all this out is a varied as the individuals that face the issues, but I know that He does indeed work these things out, even for gays and in ways that even the gay person winds up with joy and peace in their life.
