Why does God allow people to have gay feelings?

We're living in a fallen world, and every one of us is born into this world with an imperfect sinful nature. Whilst it's true that God has 'knit me together in my mother's womb' (Psalm 139:13), the Psalmist also makes it clear that 'surely I was sinful at birth, sinful from the time my mother conceived me' (Psalm 51:5). An inevitable consequence of living in a fallen world with a sinful nature is that we will all desire and long for things, which are clearly prohibited by God in the Bible. Some people will struggle with anger, others with envy, still others with hatred, bitterness, jealousy, slander, or a desire to steal, or commit adultery, or to rebel against their parents. Most people will struggle to one degree or another with lust; for the majority it will be lust over people of the opposite sex, but for some it will be lust over people of the same sex - the Bible simply calls it lust.

The gospel of Jesus Christ redeems (rescues) us from the power and consequences of our sinful natures and begins to transform us, so that increasingly, step by step, we desire and are empowered to live lives which conform to God's pattern for living in the Bible. It's worth noting that very often 'gay feelings' are actually masking a legitimate, unfulfilled need for a right kind of same-sex intimacy, affection, affirmation and acceptance.
