Love of God promotes regard for his precepts rather than blind, feel-good disregard and trampling under foot of his people. Love promotes spreading truth rather than falsehood. Love would have anyone inspect themselves and their doctrines for validity. Love is not an excuse for ambiguity, nor is it a 'mere feeling'. It is a motivation or way of behavior. Love of God, oneself and others for would promote one to adhering to sound doctrine. Of course, if you hate someone, you'd lead them astray.
