Can't get more obvious than that, can it? Jesus said he didn't come to abolish the law, but to fulfill it, so don't claim it no longer applies.
So, does that mean I think that gays should be killed? No more than I think people who commit adultery should be! They are in need of the saving grace of Jesus just as much as anyone else—no more and no less. But, just as Jesus said to the woman caught in adultery in John 8, “Then neither do I condemn you,” Jesus declared. “Go now and leave your life of sin.” (Yes, I believe John 7:53-8:11 is an authentic event in Jesus' life—I just don't believe it is Johannine.)
And, because I believe that we are new creations in Christ, I believe they can leave their life of sin. I also believe that the sexually addicted, chemically dependent, etc., are called—and enabled by the presence of the Holy Spirit—to live a life free from sin.
A good summary of the sexual life of a Christian should be celibacy in singleness and faithfulness in a monogamous, heterosexual, lifelong marriage. Anything else is a compromise and sub-Christian. That goes for adultery, divorce, and homosexuality. There is no distinction between them; they are all less than God's ideal.
Yes, there is forgiveness and restoration, so don't think I am being judgmental here. I know there are situations where divorce is the least of a set of evils, but it is still not God's ideal. I believe that is what Jesus was saying when he said Moses allowed divorce; both parties need to be willing to forgive, repent (that means transformation, not just feeling sorry), and live in love. That doesn't always happen...
