But in all honestly Zack, it depends on the person...just as some people are born with a short temper, which is a health condition..its what they do with that anger when they are angered that sin takes effect, since acting of anger in certain forms is a sin. Just as homosexuality..if you act out upon that then and you cannot help it then it is a sin, that is when you have to resist temptation.and everyone has temptation, jsut homosexuality is a different form..now for those who truly can help it, where it isnt really that big of an issue, it is their responsibility to take up the cross and with God in prayer and in mind try and come of it completely. And entire books have been written on it so it is possible to change.
Acting out in anger is considered a sin if it's directly impeding upon other people's happiness in some way, i.e. beating them, murder, etc. Two people in love and getting married does not impede upon other people's happiness unless they want it to.
It's not possible to change your biology, unfortunately. If someone's body tells them that they're only attracted to people of the same gender, that cannot change, you can only bury it, but it'll always be there. It's not like being born with a medical condition that can be treated by surgery or anything like that. It's deep in your genes and unchangeable, as far as we know.
“Mutual caring relationships require kindness and patience, tolerance, optimism, joy in the other's achievements, confidence in oneself, and the ability to give without undue thought of gain.”
