Romans 2:1-5, 12-16

Therefore you have no excuse or justification, everyone of you who [hypocritically] judges and condemns others; for in passing judgment on another person, you condemn yourself, because you who judge [from a position of arrogance or self-righteousness] are habitually practicing the very same things [which you denounce]. And we know that the judgment of God falls justly and in accordance with truth on those who practice such things. But do you think this, O man, when you judge and condemn those who practice such things, and yet do the same yourself, that you will escape God’s judgment and elude His verdict? Or do you have no regard for the wealth of His kindness and tolerance and patience [in withholding His wrath]? Are you [actually] unaware or ignorant [of the fact] that God’s kindness leads you to repentance [that is, to change your inner self, your old way of thinking—seek His purpose for your life]? But because of your callous stubbornness and unrepentant heart you are [deliberately] storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.

For all who have sinned without the Law will also perish without [regard to] the Law, and all who have sinned under the Law will be judged and condemned by the Law. For it is not those who merely hear the Law [as it is read aloud] who are just or righteous before God, but it is those who [actually] obey the Law who will be justified [pronounced free of the guilt of sin and declared acceptable to Him]. When Gentiles, who do not have the Law [since it was given only to Jews], do instinctively the things the Law requires [guided only by their conscience], they are a law to themselves, though they do not have the Law. They show that the essential requirements of the Law are written in their hearts; and their conscience [their sense of right and wrong, their moral choices] bearing witness and their thoughts alternately accusing or perhaps defending them on that day when, as my gospel proclaims, God will judge the secrets [all the hidden thoughts and concealed sins] of men through Christ Jesus. [Eccl 12:14]
