Loving it, worshipping it, and so on would be inappropriate, since those are human concepts, and nature is not human (or even anthromorphized, the way clerical deities and ideals are.)
In fact, I can see a druid clashing with a cleric of a Lawful Good or Chaotic Evil nature god (or even a 'cleric of nature'), arguing that their deities and their concept of 'idealized nature' do not reflect the true natural order and are, in fact, perversions of it.
Nature doesn't care if you worship or love it or not. A druid understands nature, and accepts nature, and has a sort of enlightened harmony with it... but they don't really worship it the way clerics worship their deities or ideals.
