Quick answer

The heart is deceitful above all things and desperately corrupt; who can truly understand it? This sober diagnosis reveals the depth of human sinfulness hidden within every person.

Overview

Jeremiah pierces to the core of the human condition, declaring the heart deceitful and incurably sick beyond our own understanding. This diagnosis explains why people trust in idols and forsake God, and it humbles every claim of self-righteousness. It magnifies the gospel, for the heart no one can know or cure is fully known by God, who alone gives a new heart through the saving work of Christ (Ezekiel 36:26).
