Homosexuality- the reason
Because of Sin, ultimately their own choice  (Rom. 1:24-27; Jak. 1:14-15)

Bisexual
Nu leh pa kop, amei leh apa hikhawm
 Numei & pasal etlah tuahna

Gay marriage
Kitenna Bible in a gen peuhmah chiangin numei & pasal kal ah ahi.
(Gen. 2:24; 1 kor.7:2-16; Eph. 5:23-33)
Bible in homosexual, lesbian, bisexual chihte phallou hi. Hiai te a phal kei leh Gay marriage kichi phal thei ngeilou ding hi.

The Gay- case
The first step, for a gay man like myself, was accepting my own sexuality as a gift from God, rather than a curse. Once I believed that it was good to be gay, I then wanted to be able to imagine a happy and fulfilling life for myself.
Jesus did seem to prefer his family of choice over his biological family and surrounded himself with a group of men and women, 12 men of whom were selected for special tutoring, three of whom were groomed for special leadership, and one of whom was described as “the one whom Jesus loved.” That is simply descriptive of what is in the text. It is better not to be too ambitious about extrapolating from that description to conclusions about what that means. But it would be hard to construe from the text that Jesus was a big supporter of a husband-wife-and-2.2 children as the only model for a family.
