Saying "God is Love"
is very different from saying that "Love is God" (Love being subject to subjective definition.)
It's also very different from "God is indulgent" which, as an overarching attitude, is anything but loving. (Especially if it means unhealthy and indiscriminate giving.) Instead, truly knowing that God loves us, in spite of our very real sin, and at the unimaginable cost of his very own Son . . . THAT is a love worth celebrating.
