You obviously cannot understand a simple argument. No one is justified by the law because at one time or another he decides to go his own way and not God's way. On the other hand, theoretically a person has the ability to be justified by his own works, as witnessed by the words of the Apostle Paul:
"For not the hearers of the law are just before God, but the doers of the law shall be justified" (Ro.2:13).
If it was not at least theoretically possible for a person to be saved by the law then why would Paul say that "the doers of the law shall be justified"?
If it was not at least theoretically to obtain eternal life by the law then why did the Lord Jesus tell the young man the following?:
"If thou wilt enter into life, keep the commandments" (Mt.19:17).
A. The preceding context (Rom. 2;1-5) deal with self-righteous hypocrits who believe they will escape judgement by their works.
B. The subsequent context (Rom. 2:17-28) demonstrates why the Self-righteous Jew will not be justified better than the heathen.
C. Romans 2:6-16 is placed right in the middle of this context of self-righteous hypocrits in order to demonstrate why self-righteous hypocrits will not escape the righteous judgment of God.
