Written in their Hearts
A Sermon on Romans 2:13-15
For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified. For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them (ESV)
The parenthesis; doing the law; not hearing it;is what counts; the Gentiles' moral consciousness proved; three false deductions about their condition; the impossibility of 'living up to our light'.
