[Ruy Dias de Bivar]

And to whom was the book of James written? “To the Twelve Tribes scattered abroad...” Still under the law, still offering sacrifices in the Temple, still practicing ritual circumcision.
Whereas Paul was “the Apostle to the Gentiles”. Free from the letter of the law, free from circumcision, free from sacrifices.
Each recognized the other’s different Gospel.

New International Version
James, Cephas and John, those esteemed as pillars, gave me and Barnabas the right hand of fellowship when they recognized the grace given to me. They agreed that we should go to the Gentiles, and they to the circumcised.

James: 1

12 Blessed is a man who perseveres under trial; for once he has been approved, he will receive the crown of life which the Lord has promised to those who love Him.

Search the New Testament. There is no promise made to anyone who remains under the Law. The only promises in the NT are to those who accept Jesus as Lord and Savior.
