Homosexual feelings are controllable. Perhaps there is an inclination or susceptibility to such feelings that is a reality for some and not a reality for others. But out of such susceptibilities come feelings, and feelings are controllable. If we cater to the feelings, they increase the power of the temptation. If we yield to the temptation, we have committed sinful behavior. That pattern is the same for a person that covets someone else's property and has a strong temptation to steal. It's the same for a person that develops a taste for alcohol.
