LB – as far as I know it is a Jewish thing. There are certainly many, many Psukim that talk about how Hashem loves us. I’m not sure where they are off-hand and can’t look right now, but I’m sure there are many posters here who can bring them.
There is actually a song running through my head. something about “ahavti eschem amar Hashem…” not sure, but I’m sure s.o. here knows what I’m talking about.
And I’m pretty sure Chovos Halevavos, shaar habitachon talks about how Hashem loves us and everything He does for us is out of love for us.
