"Snuffy" (That's a terrible name for a girl, isn't it?)
In the Old Testament, it was mostly about rules, laws, and God's Judgment. The New Testament is mostly about love and forgiveness. Learning how to love yourself, and love others.
It is not so much about how much God had grown, as about how much our understanding of God, and of ourselves has grown.
More and more we are learning that sexual orientation is something that we are born with. Many people would say the God created us that way.
There are so many people who believe that whom we are attracted to is a choice. Of course, most of these people are straight, and have never questioned who they are attracted to. The truth is, before puberty, most of us aren't attracted to much of anybody, and boys play with boys, and girls with girls.
It would be good for you to be able to talk to LGBT people, but that is much easier to do in a big city. Good luck,
"Christianity is not about what you believe, it is about how you treat other people; - with God's love"
