I can't ascertain what that even means. "God is Love," so therefore God is not an entity, not a person, only a feeling. "God is Life itself," so again, not an entity, merely a biochemical process? And, really, isn't "the highest form of the fulfilled life" an entirely individual thing?
No, it is not entirely and individual thing. Think of it in terms of "good health". Is that entirely subjective, and it can mean just about anything at all or really nothing at all? Of course not. It becomes really clear when things are working efficiently in the body. And it is common to one another, just as saying "health" has a common frame of reference to anyone who has experienced health.
All those nostrums sound good, but they really don't seem to convey any real meaning at all.
The real issue here is that for someone who has never experience good health, you might as well be trying to describe the color green to someone who has never experienced eyesight. But to those with the experience of vision, green has an actual, shared, commonly experienced referent.
These are hardly nostrums. They have actual referents that are common. The experience of "Ultimate Reality" is something that is actually understood by those who have experience with it, not as a high and lofty ideal, but a tangible, real experiential reality, just as seeing the color green is to the sighted.
I'll stay with my definition: love is an emotion, and emotions are the means through which our biological needs are brought to our attention so as to be acted upon.
Well, that is your choice of course. But I see it as highly myopic, limited, and self-ignorant of the way the rest of the world understands and uses that term in common language to mean a spectrum of things, from a type of emotional feeling, to a philosophical attitude towards living, to the highest state of mind and being foundational to all of existence itself.
"It's just a chemical". Okay. Suit yourself if it makes life easier to deal with by reducing higher level abstractions down to nothing but mere atoms and molecules with nothing else above that level being actually real. That is your given faith of choice then.
When the doctor taps just below your knee and your foot kicks, that's a reflex -- you don't need any emotion for that reaction to happen, therefore the entire event is registered in your brain only after it is all complete. Love is not a reflex, nor are hunger, thirst, fear, anger, lust -- they all require the mind to spur our physical selves to action. And unlike the reflex (you can't prevent that), you can squash the emotion and refuse to respond.
As I've said, if believing that ultimate reality, ultimate truth and light comes through understanding the world as nothing but chemicals and processes, and strip away all that other extra business above and beyond that, then that is of course your faith choice. I don't find that well-supported, or very rational myself. I personally see as a bit of a faith based on an existential fear of the unknown. But I can imagine how in some ways it brings comfort. I can only say then, may your chemistry bring you ultimate Peace.
