Queenie,
I too am a Christian. In fact, I'm currently in school for Christian ministry. My goal is to spread the Word of God and bring others to Christ.
In dealing with my own transgender feelings I too was scared of what God might think of me expressing who I am as a trans woman. After talking with others in the trans community, therapy sessions, personal reflection, and research study on transgender issues I have come to the conclusion that God does not make any mistakes. He does, however, make anomalies. Some people are born conjoint twins; some are born intersex; others are born with autism; still others are born blind or deaf; and some are born transgender. Are these mistakes on God's part? No. Would it be a sin for a person born blind to undergo a surgery that will enable him or her to see? No. While we don't necessarily know or understand God's reasons for making people the way He does, we have to believe that He loves us all very much. We each must walk the paths laid before us and learn the life lessons that He has ordained for us, and bear in mind that no two people can ever walk down the exact same path.
Some people will use the Bible as a means of condemning others and claim to be Christians. THe Ku Klux Klan is famous for quoting scripture as the reason for their activities, but yet they actively go against everything that Christ taught about love, tolerance, and caring for one another. However, bear in mind that just as all Muslims are not radical terrorists, not all Christians condemn or persecute other people in the name of God.
One final point: people have looked for reasons to persecute, hurt, and kill one another for thousands of years, religious or not. On top of this, people love to justify their actions no matter how dastardly they might be, and they will use any means necessary, including God and the Bible, to excuse their behavior. Just remember that not everyone that claims to be Christian by mouth necessarily does so by deed. Also, no matter how perfect we try to be as humans, at our very best we are "but filthy rags" to God and thus can never stand up to His standards. In matters of the Christian faith we must rely on His sufficient perfection, because all of human perfection is terribly tainted and corrupt at very best.
Hugs!!!
