Romans 2:13
If our foundation is to be on the rockmass of Jesus’ words we must be acquainted with those words. And it is here that the majority of those who profess Christianity fail. They do not even make a beginning to know because they do not have a real desire to know God. Paul, an outstanding apostle of Jesus, made this point clear and showed the results, saying: “And just as they did not approve of holding God in accurate knowledge, God gave them up to a disapproved mental state, to do the things not fitting, filled as they were with all unrighteousness, wickedness, covetousness, injuriousness, being full of envy, murder, strife, deceit, malicious disposition, being whisperers, backbiters …. Although these know full well the righteous decree of God, that those practicing such things are deserving of death, they not only keep on doing them but also approve those practicing them.” (Romans 1:28-32) People today are building on the shifting moral standards of this old world that is certain to perish when God’s wrath is expressed. “But according to your hardness and unrepentant heart you are storing up wrath for yourself on the day of wrath and of the revealing of God’s righteous judgment. And he will render to each one according to his works.”-Romans 2:5, 6.
Also James’ words: “Become doers of the word, and not hearers only, deceiving yourselves with false reasoning. For if anyone is a hearer of the word, and not a doer, this one is like a man looking at his natural face in a mirror. For he looks at himself, and off he goes and immediately forgets what sort of man he is. But he who peers into the perfect law that belongs to freedom and who persists in it, this man, because he has become, not a forgetful hearer, but a doer of the work, will be happy in his doing it.” (James. 1:22-25) So not the mere readers of the Bible, nor the mere hearers of the Bible, but the doers of the Word of life are the ones who are approved and who will be rewarded with life.
Romans 3:20
By giving the Law covenant to Israel, God made clear that all persons, not merely the idolatrous pagans but also the Israelites, were guilty of sin. It served to make the Israelites acutely aware of the many ways in which they failed to measure up to perfect standards. This was “so that every mouth may be stopped and all the world may become liable to God for punishment … for by law is the accurate knowledge of sin.” (Romans 3:19, 20) Even though an Israelite may have been free from idolatry, may have been abstaining from blood, may not have been guilty of murder, he was still declared guilty of sin by the Law covenant. This was so because the Law covenant now specifically identified a host of actions and even attitudes as sinful. Hence, Paul, viewing himself as if alive in the loins of his forefathers prior to the giving of the Law, says: “Really I would not have come to know sin if it had not been for the Law; and, for example, I would not have known covetousness if the Law had not said: ‘You must not covet.’ …. In fact, I was once alive apart from law; but when the commandment arrived, sin came to life again, but I died.”-Romans 7:7-9.
