Some on this forum want to interpret the words that no man is justified by "works of the Law" or "deeds of the Law" to mean no man must become a Jew in order to become a Christian. However, that will not cut it in Romans 3:24-5:2 as Abraham lived 430 years BEFORE the Law was given to Israel and yet Paul said he was not justified by his works. Obviously "his works" could have no possible reference to the Mosaic law. It had to do with his good or bad efforts to satisfy God or be justified before God. Therefore, how good must one be in order to be justified by God? To enter heaven? I believe Jesus answered that In Matthew 5:20 and 5:46 and James answered that in James 2:10-11 A person's WHOLE LIFE must be MORE righteous than the most pious people of the day. To enter heaven their righteousness must "EXCEED" that of the Scribes and Pharisees - Mt. 5:20 A person's WHOLE LIFE must EQUAL the righteousness of God to enter heaven - Mt. 5:46 If a person's WHOLE LIFE fails in but ONE POINT of the Law he is under the condemnation of the Law as sinner. Therefore, one must not fail ANY POINT of the Law THROUGHOUT HIS WHOLE LIFE to be justified by the Law. That is why Christ had to come from heaven and be born of a virgin in order that no sin be found "in him" and then live a sinless life so as to be 'without sin". That is why substitutionary atonement is the only possible way salvation can happen. Spiritual union with Christ does not produce a WHOLE LIFE without sin.
