That is the way we are made: we don’t reason, where we feel; we just feel (Mark Twain in A Connecticut Yankee in King Arthur’s Court)
“Follow your heart; tell him/her how you really feel” is an oft-repeated suggestion in a Hallmark movie. That’s not a new phenomenon, as indicated by Twain’s quote. It’s because we’ve confused love with feelings, but love is far more than just the feeling when you “spoon under the moon by the lagoon in June.” Genuine love cares and supports first; feelings come later.
Don’t just pretend to love others. Really love them. . . Love each other with genuine affection and take delight in honoring each other.” (Romans 12:9-10)
