Yes. God loves all existing things because all existing things, in so far as they exist, are good, since the existence of a thing is itself a good (and likewise, whatever perfection it possesses).
Although creatures have not existed from eternity, except in God, yet because they have been in Him from eternity, God has known them eternally in their proper natures; and for that reason has loved them, even as we, by the images of things within us, know things existing in themselves.
