These verses should dispel any “lost ten tribes” nonsense that makes it way around the theological circuit from time to time.
Members of the twelve tribes to whom James wrote were dispersed (διασπορά) due to attacks from Gentile powers. Many whom James (and Peter) wrote were Jews forced to flee Israel due to persecution (cf. Jews still resided in Babylon and Peter wrote sent greetings from some special woman who lived there (1 Peter 5.13).
God prophetically promised all twelve tribes will remain forever (Ezekiel 37.15-23).
…Second: Its purpose is to teach Christians, and in all this long teaching it does not once mention the Passion, the Resurrection, or the Spirit of Christ.
He names Christ several times, but he teaches nothing about Him, and only speaks of common faith in God. by Herod Agrippa I, grandson of Herod the Great (Acts 12.1-2).
But for the individual, it was effective if he believed it. The obvious, unequivocal answer is that in the Jewish economy, faith works were required for salvation.
So, forgiveness required a work (bringing an animal sacrifice) and faith (believing the sacrifice covered the sin). The Gospel of the Kingdom John the Baptist came as the herald of the King and proclaimed the gospel of the kingdom (Matthew 3.1-2).
James Wrote To Jews Despite what most of Christendom believes and teaches, the Twelve never had a ministry to Gentiles. At the end of the Jerusalem Council, the participants formally agreed to continue to abide by this state of affairs: the Jerusalem Jews and those under their leadership would minister to Jews and Paul would minister to Gentiles (Galatians 2.7-9).
This truth is revealed by the introductory address of James’ letter: A couple of things are noteworthy from James’ statement.…But this James does nothing more than drive to the law and its works; and he mixes the two up in such disorderly fashion that it seems to me he must have been some good, pious man, who took some sayings of the apostles’ disciples and threw them thus on paper; or perhaps they were written down by someone else from his preaching. Paul calls it a law of slavery, (of wrath, of death and of sin, Galatians ; Romans ). This study will reveal why James wrote what he did and resolve the problem of faith and works. The author of James was James the Just, a half-brother of Jesus (Galatians 1.19), not the Apostle James, the son of Zebedee, who was one of the twelve apostles. Perhaps, following his death, James replaced the Apostle and assumed his place of prominence.In any case, James was not one of the original Twelve and was, therefore, a second-order apostle. Paul and all the rest of Scripture, it ascribes righteousness to works, and says that Abraham was justified by his works, in that he offered his son Isaac, though St.Paul, on the contrary, teaches, in Romans 4:2, that Abraham was justified without works, by faith alone, before he offered his son, and proves it by Moses in Genesis 15:6.For us, looking back, they reveal how God was laying the groundwork of a greater reality than animal sacrifices.
