hi there!

sorry i was debating over answering this question or not, but i do believe it is a sin to be gay. in the beginning, god created man and he created women to be a for man. there are many "political" views on this topic but i believe the bible is right. in the kjv bible, leviticus 18: 22, god talks about how it it is an abomination for women to be with women and man to be with man. god knows that everybody is a sinner, and he gives everyone a chance to repent. i'm not forcing god's word on anybody, but i do believe it is a sin. no matter the sin, as long as you repent, god is willing to forgive, you just have to accept him as your lord and savior.

nature versus humanity!
