I don't know as I could actually use the word "honesty" in the context of me first thoughts on your question.
I can't, of course, claim I have always been totally honest before God But on the whole, I don't think that's part of how i worked this ting out in terms of my faith.
For most of my life, I bought into the (man made) doctrine that what was wrong with me was a perversion - somehow I had been infected with a sinful desire. Clearly that was counter to God's will, so if I simply "got right" with him, he would "heal" me of my perversion.
After 20 years of that, and no healing in sight, I began to - for other reasons at first - re-examine my understanding of how much of what I believed was actually God's expressed will and how much was a cultural schema that was the product of man's society.
I now see being trans as, if you will forgive the term, a "birth defect" and no more a function of being outside God's will than if I had been born with spina bifida or a cleft pallete.
but in the former days, I was always very upfront with God saying I didn't want to be out of his will and begging for his help, and when I began to realize my error, I had a long frank "talk" in which I basically said that I was acting in light of my best understanding and not looking for an "out" to disobey. I suppose one could argue (from the conservative point of view) that I am blinding myself but all I can do is examine my own heart and i believe I'm acting in honest good faith.
Beyond that, I do believe that grace is the foundation of our faith. If he's not the God of grace I understand him to be then following him is, for me, useless. So I have every confidence his grace is big enough to handle my failure, when (not if) I fail.
Further, without airing dirty laundry inappropriate to this board, I confess that in other areas I am doing what my more conservative brethren would call "presuming on his grace". Perhaps it's an over-correction for so many years of being so over-zealous and there will be a balance between the two at some point but for now, I'm a long way from "clean living"
but even in this, I try to be honest with him. I am either right that he is not nearly as uptight about sexual behavior as the church is, or i am rationalizing. If It's the latter, his grace is big enough to cover my logical weakness.
Make of that what you will.
