If you want to have a discussion here you should try harder.
edit: let's just play the game, shall we?
"God is Love", first of all - is this a definition of God or one of love? I have a feeling it's trying to be both, but that is invalid. It's probably trying to tap into some intuitive understanding of what "love" is and to connect it to some other concept, such as God.
In any case, a) we haven't defined what "love" is and that's not gonna be an easy definition - maybe we should start there; b) suppose we know what love is: if you say "God is love", and you use that as a definition for God then... why do we need a concept of God? We can just go and rewrite the entire bible and substitute every occurrence of God with "love"? So, in the beginning, love created the universe? Love died for our sins? Love sent the great flood and told Noah to build an ark? Even if you don't take these stories at face value, the bible clearly ascribes agency to God, but if God is just love, then love supposedly has agency something that... probably doesn't make sense with most people's definition of love. See point a)
I would suggest for you to pick up an introductory textbook to some topic in analytic philosophy and compare the rigour of the explanations therein with "God is love".
That's because it doesn't mean anything.
