In all honesty, I am not sure that God would mind if someone was gay, and this is because he is all loving, benevolent and equally encourages all of his children as brothers and sisters in Christ to love one another unconditionally.
I take into consideration the elements of grave sin, but at the same time ‘Thou shalt not lie’ was one of the Ten Commandments. Therefore, if someone is gay and they refuse to admit this and act on it for fear of how they will be perceived due to something they did not choose in the first place but is an intrinsic part of them, this will encourage them not only to lie to others but, far worse, they will lie to themselves.
At the end of the day, God loves us. We are all, each of us, perfect to him as we were made in his image. Therefore, an all-loving God would accept any relationship be it man and woman, man and man or woman and woman, provided it is a genuine, all loving relationship. And in general, as long as each relationship is legal, consensual between adults I cannot see the problem. After all, there are marriages between men and women which are abusive and unequal, and I cannot see our all loving God seriously condoning those ones.
