Therefore you are inexcusable, O man, whoever you are who judge, for in whatever you judge another you condemn yourself; for you who judge practice the same things. 2 But we know that the judgment of God is according to truth against those who practice such things. 3 And do you think this, O man, you who judge those practicing such things, and doing the same, that you will escape the judgment of God? 4 Or do you despise the riches of His goodness, forbearance, and longsuffering, not knowing that the goodness of God leads you to repentance? 5 But in accordance with your hardness and your impenitent heart you are treasuring up for yourself wrath in the day of wrath and revelation of the righteous judgment of God, 6 who “will render to each one according to his deeds”: 7 eternal life to those who by patient continuance in doing good seek for glory, honor, and immortality; 8 but to those who are self-seeking and do not obey the truth, but obey unrighteousness—indignation and wrath, 9 tribulation and anguish, on every soul of man who does evil, of the Jew first and also of the Greek; 10 but glory, honor, and peace to everyone who works what is good, to the Jew first and also to the Greek. 11 For there is no partiality with God.
12 For as many as have sinned without law will also perish without law, and as many as have sinned in the law will be judged by the law 13 (for not the hearers of the law are just in the sight of God, but the doers of the law will be justified; 14 for when Gentiles, who do not have the law, by nature do the things in the law, these, although not having the law, are a law to themselves, 15 who show the work of the law written in their hearts, their conscience also bearing witness, and between themselves their thoughts accusing or else excusing them) 16 in the day when God will judge the secrets of men by Jesus Christ, according to my gospel. — Romans 2:1-16.
There is an inevitable and eternal consequence of our response to God. God is equal-handed in applying a simple but vital test. Those whose lives manifest their faith in Christ, by patient continuance in doing good and seeking God’s glory and honour, will for ever know His eternal life. Those who, with hard and impenitent hearts, continue in their self-seeking and sinfulness as they disobey God’s truth, must expect God’s wrath as a result of His righteous judgement. God impartially looks in judgement at both Jews, who have received His law externally, and at Gentiles, who have not.
The truth is that there is a natural law written in the hearts of men which includes some knowledge of right and wrong instinctively, even though that is not as finely tuned or as well detailed as God’s written law. Thus Jews, with the law, or Gentiles, only having the law which is written in the hearts of all men, are equally to be judged by God who knows their secrets. Jesus Christ will, one day, judge those secrets according to the preached gospel. [Sourced from The Bible Panorama.]
