I think that a homosexual comes to the text with major presuppositions about what they both want to and expect to walk away with from scripture. I think that this is true for all people if we are not careful. Even Bill Clinton found a way to support receiving oral favors using scripture. (its not sex; yeah sure.)
I do agree that although homosexuality is not the major core value of scripture nor is it the bible's ultimate theme (of course) it is still a value that God takes serious. Do I think all homosexuals go to hell. NO WAY!! God's grace surpasses more than we can comprehend and only God knows the heart, and is qualified to judge it. However, it is hard for me to get past all of the scripture on Sexual Immorality (all sexual immorality, not just homosexuality) and to walk away thinking that when God see's 2 men or 2 women (who are not married) having oral sex, anal sex, hand sex, or whatever else we can dream up; that he rejoices and dances over that act like he does when a married man and women come together as 1 like it is stated in Genesis. I just cannot find that in scripture.
Add to that the harsh words from Paul in 1 Thes 4:3-8 which says It is God's will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen, who do not know God; and that in this matter no one should wrong his brother or take advantage of him. The Lord will punish men for all such sins, as we have already told you and warned you. For God did not call us to be impure, but to live a holy life. Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit.
Verse 3 is clearly stating that the way we deal with our sexuality has a direct impact on God's sanctifying work in us. It is also agreeing with what all of us would say, which is, "at times we will have to fight our own un-natural sexual urges for the cause of Christ in order to inherit all that Christ would desire for us to have." I want to make very clear that sexual urges are not all un-natural, but urges that I would say the bible considers un-holy or not honorable (sex before marriage, sex outside of marriage, same sex sex, sex with animals, etc) are un-natural.
Sex is a great thing created by a great God. Actually when people tell me that they believe God isn't good, I remind them who created sex (oh yeah baby); is it even possible for the creator of sex to not be good? I don't think so.
I will end with this comment. Luke 14 says that in order to be considered a disciple of Jesus we must Love him more than anything else; including our pleasures. We must be willing to carry our cross and be willing to die. Revelations 2 say that we are to be faithful even until the point of death. These scriptures point out a very hard truth and that is, more often than not, we will be faced with making decisions that go against our feelings; our gut; our pleasure; what looks right; what feels right; etc. However, in order to be able to be called one of Jesus' true disciples, we need to die to self and live for Christ. For me that means, no sleeping around regardless of how good or bad my marriage situation, no lying no matter how much the truth hurts, no cowering under the pressures of culture because it is easier; instead, now that I am a Christ Follower with a transformed heart and a renewed mind, I need to Die to Self and live for Christ.
The call is hard and although the grace of God is a free gift, it will cost us EVERYTHING.
