Just because someones gay doesnt mean they arent christians...No one just wakes up one day and decides to be gay...god obviously made them that way. No one chooses to be gay. if you believe in god...and you go to church and live by gods book...your christian. end of discussion.
Its something (dont hold me 100% on this) it says if ur partner has cheated then its ok...because my dad got a divorce and we really looked into the whole divorce thing in the Bible...& well my mom cheated on my dad...
