No, same gender relationships are not immoral by definition. You still havent made that case, other than to keep repeating "same gender relationships are immoral by definition." Sexual or not isnt the point. The sexual ones are no less moral than straight sexual relationships. and the non sexual ones are no less or more moal than opposite sex non-sexual relationships are.
Is that really what excites you? People's hopes being shattered and being damned to eternal hell? The only reason I'm looking forward to your 'hope' being shattered is that God has something so much better in store than what a small vindictive bitter human mind like mine or yours could come up with.
I may get to the restoration of all things matter in another thread. It derives from the verse in 1Cor 15:28 that indicates that through Christ, all God's enemies will be subjected to Him, and He will be "all in all." You cant be seperated from God if, in the end, He is all in all. Do you really think something as small as death and evil (which is only emptiness and ignorance, and which has no substance) can hold out into eternity against the perfect and good God?
As I said, you're in for a suprise!
