Saw a comment on FB today along the lines of: "I hate it when people say, 'I love you because Jesus told me to love you.' That makes it sound like a duty or an obligation. Don't love me unless you want to love me."
Dude, you got so much love in your life you can afford to throw any of it away?
Don't confuse love with sloppy sentiment. Sloppy sentiment is the tingly feeling you get standing next to your main squeeze, the warm fuzzy feeling when you step through the door of grandma's house & smell the stuffed cabbage/sauerkraut/kimchi.
Nothing wrong with that feeling, but it's an adjunct to love, not love itself.
Love is a conscious decision made before the fact to demonstrate genuine concern and compassion for another person.[1]
I guarantee there is no way to force someone to love another person.[2] If someone says, "I love you because it is my Christian duty to love you," then they indeed are most certainly saying they want to love you. They are saying, "You are important enough to me to love because I was important enough to the Christ I worship for Him to love me."
To a person dying of thirst, what does it matter if the water is given freely as a gift or as a duty, so long as they get the water? Anyone who gets persnickety over the motives people have in loving him/her is in dire, dire need of love, 'cuz they sure ain't showing any.
Folks, take what you can get. Rejoice and be glad in it.
