Is God The Actual Entity of Love?

In the Christian Bible, the Apostle John twice says that "God is Love." No where else do we find those precise words.

Most people assume that simply means that God loves us. After all, the Bible says that in other places. But, while it is true that God loves us, this short book suggests that John did not just mean that. It suggests that John's meaning may be well beyond that.

Is it possible that John meant that God actually IS Love? That God is the ENTITY of Love? This book suggests that may indeed be what John meant.

But how, one might ask, could a book about God as Love possibly lead to controversy?
