God created man and woman to be in union. Christ's NT teaching affirms this is to be faithful. Thus there is no such thing as gays or straights in the Kingdom, just men and women who are created in God's image for His purposes.
LGBT philosopy sets people apart and creates the idea that God doesnt love them. It also tells them they are different and God created them different. The message is evil, the man or woman who experiences same sex attraction is no worse or better than than the man or woman who experiences adulterous desires or temptation to any other sin. Normally as Christians we confess or teach something is wrong, ie lying or theft or adulterous thoughts, but go away privately to repent when we end up lying or stealing or having adulterous thoughts. Yes the struggle will be difficult for those with same sex attraction, but the key is knowing what is sin and confessing, NOT the falling short which we all do from time to time.
I am hearing too much these days of 'do Christians understand the despair of homosexuals. The answer could be do homsoexuals understand the despair of single people who have never found anyone to marry? The gospel of Jesus Christ is hope, and forgiveness of sin, not despair. I once saw a gay lobby group, the inclusivechuch I think, say that if same sex relations arent allowed then the gospel isnt good news for homosexuals, and the answer to that is they obviously dont know or believe the gospel of Jesus Christ.
And I suggest many more Christians have an ongoing battle against greed that is even more a struggle than wrong sexual desires.
If we confess what is sin, including same sex sexual relations then we have the truth, and it is the truth that sets us free.
