12 All those who have done wrong without the law will get destruction without the law: and those who have done wrong under the law will have their punishment by the law; 13 For it is not the hearers of the law who will be judged as having righteousness before God, but only the doers: 14 For when the Gentiles without the law have a natural desire to do the things in the law, they are a law to themselves; 15 Because the work of the law is seen in their hearts, their sense of right and wrong giving witness to it, while their minds are at one time judging them and at another giving them approval;

Commentary on Romans 2:1-16
(Read Romans 2:1-16)
The Jews thought themselves a holy people, entitled to their privileges by right, while they were unthankful, rebellious, and unrighteous. But all who act thus, of every nation, age, and description, must be reminded that the judgment of God will be according to their real character. The case is so plain, that we may appeal to the sinner's own thoughts. In every wilful sin, there is contempt of the goodness of God. And though the branches of man's disobedience are very various, all spring from the same root. But in true repentance, there must be hatred of former sinfulness, from a change wrought in the state of the mind, which disposes it to choose the good and to refuse the evil. It shows also a sense of inward wretchedness. Such is the great change wrought in repentance, it is conversion, and is needed by every human being. The ruin of sinners is their walking after a hard and impenitent heart. Their sinful doings are expressed by the strong words, "treasuring up wrath." In the description of the just man, notice the full demand of the law. It demands that the motives shall be pure, and rejects all actions from earthly ambition or ends. In the description of the unrighteous, contention is held forth as the principle of all evil. The human will is in a state of enmity against God. Even Gentiles, who had not the written law, had that within, which directed them what to do by the light of nature. Conscience is a witness, and first or last will bear witness. As they nature. Conscience is a witness, and first or last will bear witness. As they kept or broke these natural laws and dictates, their consciences either acquitted or condemned them. Nothing speaks more terror to sinners, and more comfort to saints, than that Christ shall be the Judge. Secret services shall be rewarded, secret sins shall be then punished, and brought to light.
