Yes. II Timothy 3:16-17 says, “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.” II Peter 1:3 says God has given us “…all things that pertain to life and godliness . . .” The book of James, therefore, is sacred scripture which pertains to life and godliness and is PROFITABLE, for doctrine, reproof, correction, and instruction in righteousness!
There have been, and are those, who make light of and do their best to discredit the book of James because they do not like what he says about the relationship between “faith” and “works.” They have their preconceived ideas, which are false to the core, and therefore go to the scripture in a futile attempt to try and build their case around their false doctrine. When they come to a scripture that drives a death nail into their coffin of devilish doctrine, the best approach they have is to simply dismiss it, reject in and cast doubt concerning it. They obviously cannot deny what it says without making themselves look like an infidel and lose support of followers, so they just deny its credibility. But neither of these approaches offers any consolation to those who seek to deny the very word of God. A woe of condemnation is pronounced upon their head in Revelation 22:18-19. Martin Luther, nearly 500 years ago, cast doubt on James because he considered it to contradict Paul in Romans 4. He called the book “a right strawy epistle.” Shame and disgrace is heaped upon any man who denies inspiration!
There is a beautiful harmony between the book of James and every other book of the Bible. They go hand in hand. Actually, James serves as an inspired commentary in explaining in more detail what Paul said about Abraham’s justification. Both use the same account in Abraham’s life (Genesis 15:6) to show the harmony of “faith and works.” Paul tells HOW Abraham was justified (by faith, Romans 4:3) and James tells WHEN he was justified (when he worked obedience, James 2:21). James picks up where Paul left off.
