Direct Answer
Based on the transcript, the danger is turning Jeremiah 2:13 into a generic slogan about effortless salvation, which the speaker says misses Jeremiah’s actual point: God is calling His covenant people to repent from idols and return to obedience as their life-source. When “living water” is detached from obedience, we lose the passage’s call to repentance and its warning about life-draining substitutes.
