Emotion is sometimes a good view into spiritual realities, but one has to look at the foundation of the realities.
The idea that “I am mine” is as old as the fall in the Garden. And it isn’t even a true idea; the Serpent was behind this, remember? Believing in him got man there and keeps man there. Believing on God who now offers a superior promise to the false, fraudulent promise of the Serpent — that of forgiveness, cleansing, and salvation — pulls man away from this fallen condition.
It’s the “I am mine” that gets the emotions going in most modern women of this godless age. Those women view the ones who still carry a genuine Christian world view as odd, weird, suckers and losers.
Also this is a clue that to make headway in this, we need to make headway in quite another area first. That area is the gospel.
Yes, I debated whether or not to use the argument that ALL life belongs to God, the Creator. I find it staggeringly arrogant that anyone would presume to have authority to take an innocent life.
Although my religious beliefs inform and shape my opinions, I don’t assume others are similarly affected by the same beliefs, so I try to base my approach on an appeal to their moral logic (I know, the concept of morality does not exist outside the existence of God, but that is a different discussion). I will use the authority of God, as i did in my hypothetical talk to my niece, when speaking to a believer. But I find it more difficult to be persuasive of either argument if I combine the two when speaking to a nonbeliever, and I always make the assumption that a person who supports abortion is a nonbeliever.
I appreciate you taking us back to the “I am mine” fallacy and its birth in the Garden.
