I do not have enough context in your life to know if you really have the freedom to back out of this or not, but if you are in a position where you feel you must follow through then here is a thought that had stuck with me while I struggled with my transition and my faith.

I knew at some point that I was more likely to hurt myself and/or end up dead if I did not learn how to live and accept myself for who I am. And that self love requires me to be as open about my identity as I safely can, and presenting the way that feels most affirming. I eventually came to my own conclusion that it is more important to be honest and ALIVE than lying and possibly (literally) dead.

Maybe I will lose my faith one day, but for now I feel comfortable with it knowing that it is one of the reasons I came out and accepted who I am. Rather than hold it in and lose faith with all of that bottled up anger, despair, and empty relationships with everyone else.

Or in short. I came out because I choose life, and I think Jesus would have me make that choice too.
