Do you feel like you were born in the wrong body? Probably not, but we all know that there are people who do. What if the truth was that each one of us is trapped in our bodies? And that these bodies are not really right for any of us? What if I told you it has nothing to do with sex/gender, but everything to do with being human?
God doesn't make mistakes, but we do. In fact, we sin. And from the moment that the very first human beings turned away from our Creator, our bodies began to unnaturally decay. He had designed us as immortals, but that required staying in harmony with Him, which meant relying completely on him, trusting him, and obeying him. Once we turned to our own selves instead, our nature changed - spiritually and physically. Our fallen wills birthed death, and our bodies became enslaved to mortality.
What does that have to do with gender confusion? After the fall, though we were born with a sinful nature into flawed bodies, we were also born with a longing for our original sinless state and a yearning for our Creator. But those desires are not fully processed in our minds. The longing is unexpressed within us, and it can easily be misinterpreted. Our natural tendency is to apply it to our earthly existence, especially if we don't believe in a personal God who created each of us.
For some, faulty biology becomes the explanation for their feelings of unfulfillment. The grass becomes greener on the other side of the gender divide. Psychological factors and societal stereotypes cause some people to have negative associations with their own sex and to identify with the opposite sex. Add to that the powerful spiritual component of the longings I defined above, and you have a recipe for gender dysphoria.
Instead of realizing that no amount of biological alterations (all of which only add up to counterfeiting the opposite sex) will satisfy what are really the longings of the soul, these desperate, confused individuals believe that transforming their outward selves will bring peace to their inner selves. The argument can be made that this is also true of those who have eating disorders, obsess over hair/make-up/fashion, are exercise fanatics, get cosmetic surgery, or practice extreme sports. By making the body the focus of one's identity, that person grossly misplaces the longing meant to cause them to seek their true self in the One who made them and can save them from the identity crisis.
We will never be fulfilled this side of Heaven, but we can begin to become who we were made to be, even despite these faulty bodies, and even faultier minds. This can only happen if we stop listening to our inner voice of the almighty self and start seeking the still, small voice of our Creator, who made us in His image. Surrendering to our Creator begins with acknowledging our need for a savior. We find this One whom our hearts desire in a book - a very old book that is brimming with life and hope and the promise of eternity with new bodies...
"For we know that if the tent that is our earthly home is destroyed, we have a building from God, a house not made with hands, eternal in the heavens. For in this tent we groan, longing to put on our heavenly dwelling, if indeed by putting it on we may not be found naked. For while we are still in this tent, we groan, being burdened—not that we would be unclothed, but that we would be further clothed, so that what is mortal may be swallowed up by life. He who has prepared us for this very thing is God, who has given us the Spirit as a guarantee." ~1 Corinthians 5:1-5
"So is it with the resurrection of the dead. What is sown is perishable; what is raised is imperishable. It is sown in dishonor; it is raised in glory. It is sown in weakness; it is raised in power. It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body." 1 Corinithians 15:42-44
"But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body, by the power that enables him even to subject all things to himself." ~Philippians 1:1-3
"Beloved, we are God's children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is." ~1 John 3:2
