John Wesley on Jeremiah 9:24

Knoweth - Whether we make any curious distinction between understanding God, as if that be more speculative, whereby we rightly apprehend his nature; and knowing God, as if that be more practical, as directing the conversation, we need not here enquire; yet certainly both center in this, that we so know and understand God as to trust in him, and depend on him alone in all conditions. Exercise - Kindness, as it relates to his own people; judgment, in punishing the wicked; righteousness, as he deals justly and uprightly with both.
