I can accept that God is love, afterall, isn't love 'divine'? We have all known, felt, and given love. That is where it should end.
But inevitably, the pronoun 'He' (or 'She' as some do) is attributed to 'God' at some point by believers and this alters the metaphor, bringing gender and therefore some sort of personhood or 'being' into the definition. At some point, original sin/'you are a sinner', judgment, and punishment enters the fold. I particularly find this occurs when believers aren't winning a non-believer over to their delusional faith argument and they begin to get annoyed or angry.
The Bible defines God as more than love. It defines God as male, warrior, creator of light, dark, peace, and evil, creating things in an incorrect/impossible physical order, 'Heavenly Father', misogynist, abuser, mass murderer including baby killer, condoning slavery, and exhibiting parental favouritism to name a few traits. Whatever the Jewish faith defines as God, its Torah includes some of what I just listed.
If we define God as love, why is the Bible or any other holy book required? Why is religion needed? I don't see these as requirements to have love. I actually find them to be a detriment in a lot of cases ... and not just JW ones either.
