Try this:

You have heard that it was said, You shall not commit adultery. But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.
(Matthew 5:27-28 [ESV])

The problem comes when you deny that temptation that is allowed to grow in the heart, for such is what is called 'orientation' is, and rule your life. To identify with a sin, as those who describe themselves as homosexual do, is to say that it is their master. Those who describe themselves as LGBT have already given way to sin.
