There are people who have become Christians and daily fight the homosexual urges. So there is hope for them. You might want to research how this was accomplished.
I would point out to them the Biblical passages about homosexuality and tell them you are bound by the word of God. That is not homophobic. That is putting God first. I take it they are not Christians. Therefore they might not want to hear it but they need to understand the word of God is what you as a minister must follow in spite of your affection for them.
I agree with this post except for the part that I bolded and changed to red. I would say that following the Word of God would not be in spite of one's love for sinners, but would actually be an act of love toward sinners. I think following the Word of God is the most important act of love we can do for the lost.
Edit: Unless you meant something along the lines of "I like you and everything, but I love God more." In which case, yeah, I agree with this post.
