Fear your own hardness of heart more than anything else. Beware of rigidity, ingratitude, a demanding spirit. Beware of an unmelted heart that is never satisfied. Beware of a mind that looks for excuses not to believe. Beware of the impulse that always finds a reason to delay a response. Beware of thinking how the sermon applies to someone else. God watches how you hear his Word.
Ray Ortlund, Jr in his commentary on Isaiah
