This post is a bit of a deviation from my usual format, and it may make some of my readers uncomfortable. Before I begin, if this content offends or discourages you, I apologize and I promise that I have no such intent in this post.
Let me open up with something that happened to me.
I forget how it came about, but I wound up having a discussion with a therian friend of mine about Adam and Eve. The friend argued that in Genesis chapter 2, while Adam was looking for a worthy companion amongst the animals and could find none, he should've chosen the wolf as his companion (thus creating a grey area insinuating that he should've mated with the wolf (eww) or that he would've never sinned if he'd not needed Eve).
To most others, this notion would be hilarious (no offense intended, friend). However, to me, I was infuriated. I couldn't fathom how someone could come up with such theology to attempt to support a therianistic viewpoint. Fuming mad, I left my computer and went outside to think. I wanted to know the real reason why I was mad.
I stood outside in the freezing cold and in the dark, and prayed. I asked God to search my heart and show me why I was so upset with my friend for his views. I came to find myself angry not because his theology seemed so unsound, but because somewhere in my head, it sounded like something I somewhat wished myself (remember, I was a totemist for a long time). That led me to ponder--why did God make me human?
Let me throw some verses out here:
Romans 9:20-21: But who are you, a human being, to talk back to God? “Shall what is formed say to the one who formed it, ‘Why did you make me like this?’” Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use?
This points out that God created us the way we are for a reason, and that because God is perfect and makes no mistakes, we are no one to tell him that our present form is a mistake on his part.
Jeremiah 1:5: “Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations.”
In-context, it's not saying that God has appointed us to all be prophets or teachers. It is however noting God's sovereign plan for our lives--one that was set in motion for us before we were even created.
Psalm 139: 13-16: For you created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well. My frame was not hidden from you when I was made in the secret place, when I was woven together in the depths of the earth. Your eyes saw my unformed body; all the days ordained for me were written in your book before one of them came to be.
This verse notes the intricate way in which God created us and the care he took in doing so. God didn't just slap a bunch of limbs together or regurgitate us into existence--he put us together intricately, and planned out our days.
Passages in scripture flooded my mind as I pondered my humanity. Why did God create me as a human? What purpose did he have in doing so?
I reasoned that, just as God plans out the days of his creations, he could have very easily seen what my life would've been like as a wolf or any other animal. He likely saw that I wouldn't be able to draw or sing or learn Japanese, or do any of the other things I can now. I would have family still, sure, and I may even have fallen in love. But my creativity, my ability to express myself in eloquent or artistic ways would not exist, nor would any such desire be present. You don't exactly see wolves playing Mozart or recreating the Mona Lisa!
God created us as we are because he saw the lives we would live, what we would learn, what we would do for His Kingdom in our own unique ways... the span of our lives as humans reflected his glory best--that's why we're human.
If you're not a theist, then consider this: If you're a therian and assume that your life would've been better if you weren't human to begin with, or that you're destined to lose your humanity somehow one day, what will you no longer be able to do that you can do now? If you can draw, will you be able to draw anymore? If you can sing, will you be able to sing anymore? If you can write stories or poetry, will you be able to do any of that anymore?
Humans are the only ones who can create and express themselves in such beautiful ways... why give that up or want to throw it away?
