From the Diary of Anne Frank:
"Love, what is love? I don't think you can really put it into words. Love is understanding someone, caring for him, sharing his joys and sorrows. This eventually includes physical love. You've shared something, given something away and received something in return, whether or not you're married, whether or not you have a baby. Losing your virtue doesn't matter, as long as you know that for as long as you live you'll have someone at your side who understands you, and who doesn't have to be shared with anyone else!"
Note the emphases. People don't talk like this anymore. She draws an equivalence between physical love and having a baby-heck, she calls it "physical love". She also talks about the idea of saving yourself for someone and continuing to belong exclusively to that person. Morality isn't found in the way people speak anymore. The way people speak is important. It's not just what you come right out
and say in the way you speak, but also what is implied by the way you
speak and the ideas on which your manner of speaking is based.
We can expand on that idea of exclusivity by saying that God created you for the purpose of calling you to marriage with that person. He created you to be specifically with that person and that person specifically to be with you and that your whole lives you should be saving yourselves to belong exclusively to each other at the time God appointed. Why? Because God deserves it. God deserves to have His creation function according to the plan for which He created it. It's as simple as that.
And to think, she didn't even have a Christian upbringing (obviously) and she could figure this out! Although, after trying to comment on love myself (it's ultimately the whole point of this blog), I can say that the first remark I emphasized is the most true of all in that quote. Love is ineffable because Love is God-real Love, not some sort human emotion (although emotion does mimic some properties of Love since the whole point of promoting emotional pleasure is to lead people into sin).
