Sounds like something said at a funeral.

Sounds like convoluted nonsense to me.

Yeah. I think It's right on. I think even as a atheist, there are unanswered questions about the nature of life and consciousness. There doesn't have to be a sky daddy or universe mother at the other end of it. Let's deconstruct:

Life is eternal: Well, our short lives may not be... but life has been persisting for billions of years and doesn't show any signs of stopping. I'll count it... even though 4 billion years isn't anywhere close to eternity.

Love is immortal: Well, the concept of love lives in the minds of living things, yet unrestricted to any particular body or circumstance betwixt individuals. It would be challenging to prove "love" is really alive in the first place... so kinda hard to prove it can die, we can count this too.

death is only a horizon: Well, this is probably the most dubious and misleading part... but using the apersonal logic utilized in my previous two arguments, I can suggest that if we do not limit our assay of death to individuals, than I think we can provide a context where death is a "horizon". Death, after all is evolution's eraser. It's the way we make room for new bioforms who wait beyond the precipice of present living populations. We have to get a little poetic about it... but okay, we can call death a "Horizon".

A Horizon is nothing save the limit of sight: Probably the strongest statement in the bunch. Hard to refute that one! It's a good reminder. This is how I see the Big Bang or the edge of the Observable Universe. Not genuine limitations (edges) of the universe at large, just a limitation (edge) in human perception.

It is a beautiful quote, with lovely sentiment, but that doesn't mean it's true. Take things for what you feel and believe. No need to get defensive about things we disagree with in a literal sense. I think some of the Psalms are beautiful, the fact I am a secular humanist doesn't change the beauty of the words or thoughts.

My thoughts, Bullshit!

We have a word for this sort of thing in the UK, it's Bollocks.

I don’t understand what it means

It's a beautiful quote ... that I don't believe in. Life is definitely not eternal. Love is definitely not immortal. Death might be only a horizon. Won't know until I get there. And still won't know if the atheists are right and we just cease to exist.

My quote would be: Life is precious, and love is wonderful for however long it lasts; and death is still the great mystery.

It sounds nice, but I wouldn’t say it’s accurate.

I think, I think, I am I think !
