It's called the salvation of the soul. It is the work of the Lord Jesus and according to the will of the individual. The Holy Spirit's job is to convict of sin. We can point out the truth of God's word but we are not permitted to bully, intimidate or frighten people into a false repentance.
Satan hates everything to do with God's amazing creation, especially the human race. His "gender blender" assault on human sexuality is a direct attempt to destroy the image of God in mankind. However, it is not the only sin and focusing on it alone is counter productive.
There are stages to freedom. It is not "therapy". The root cause of homosexuality is rebellion, as is made clear in Romans 1. The first sin was disobedience and every other sin is an act of disobedience. Unless an individual recognises the reason for his/her bondage, or even that it is a bondage, then there is no point in trying to help them.
Satan has deceived people into thinking that they cannot change, that homosexuality is like the colour of your eyes and you are just born with it. That is utter rubbish. People are not born murderers or thieves. Sin is sin and needs to be confronted as such. Once the person agrees, we need to encourage them to walk in the freedom that Christ died to give us. That is not easy because (as is obvious from this forum) not so many know that freedom themselves. Free people can free people! (Robert Morris said that). And yes, there is a homosexual demon that has to be cast out.
I have a personal interest in this. One of the most talented and capable men I ever met was homosexual. He was saved, got married and had two kids. He backslid and went back to his former lifestyle. He died of AIDS. He repented before he passed away, but it was the waste of a life that could/should have been so much more.
