Do you mean "differing," and not "deferring"? If not, then please further clarify.
Deferring.
Romans 3:26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. 27 Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.
Romans 11;5 Even so then at this present time also there is a remnant according to the election of grace. 6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
We are saved by faith in Jesus Christ without works whereas deferring from those that say faith without works is dead as if applying to that faith in Jesus Christ for salvation when James was talking about the church's supposed faith in God to provide to the poor & rebuking the church for applying that faith in God to provide for the poor to get out of helping the poor that were in immediate need for food & clothing.
James is writing about the relationship between faith and works from a context different than Paul and James is explicitly writing about the life of faith and works in the lives of the already saved, NOT the yet to be saved. NOTHING in James' epistle has anything to do with soteriological conversion from death to life; not a single word of it. The entirety of his commentary in James 1-2 is that solely of the already regenerate convert writing to the already regenerate convert about the already regenerate convert. Absolutely nothing in those two chapters is about how the already regenerate convert went from being an unregenerate non-convert to a regenerate convert. Nothing. The entirety of James' commentary is about the place of faith and works in the life of the post-converted believer. He opens the letter calling himself, "a bondservant of God and of the Lord Jesus Christ," and writing to the "twelve tribes," calls his readers his "brethren," adding, "In the exercise of His will He brought us forth by the word of truth, so that we would be a kind of first fruits among His creatures." His readers are the brethren of first-fruit bondservants in Christ, not non-believers.
Doubt me? Get out your Bible and read the text for yourself. Pay close attention to any mention of anyone who is not already a Christian. You will find there are no such mentions. Not explicitly, not implied, not remotely insinuated. None.
(Paul, on the other hand, is much more diverse in his expositions. He writes about both the not-yet converted and the already-converted. The two should not be conflated)

I would ask you to revisit the issue in James 2nd chapter with Jesus Christ as James was never talking about faith in Jesus Christ but rebuking the church for applying verbalizing their faith in God to provide for the poor to get out of helping the poor. This is how and why it is the church's faith that will not profit the poor nor save the poor when in the eyes of the poor, the church's faith in God to provide is dead.
Do not use commentaries but seek wisdom from the Lord.
James referenced Abraham and Isaac as an historical example of the kind of faith he was talking about in how God provides for His servants. The name of that place proves it.
Genesis 22:7 And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering?
8 And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.
13 And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son. 14 And Abraham called the name of that place
Jehovahjireh: as it is said to this day, In the mount of the Lord it shall be seen.
Since James & Peter share the right hand of fellowship with Paul proves many believers are applying the words of James' wrong.
Galatians 2:7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter; 8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles
9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
So there was an agreement that they all shared the same gospel otherwise Paul could not say this earlier in that same epistle.
Galatians 1:6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: 7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. 8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. 9 As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed.
Paul did say this in how Abraham was actually justified by believing God and not by works.
Romans 4:1 What shall we say then that Abraham our father, as pertaining to the flesh, hath found
? 2 For if Abraham were justified by works, he hath whereof to glory; but not before God. 3 For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. 4 Now to him that worketh is the reward not reckoned of grace, but of debt.
5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. 6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works, 7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered.
So there are just grounds to revisit James words again in Chapter 2 as James was rebuking the church for disrespecting the poor in showing favoritism to the rich from the beginning of that chapter and goes on to expose how they try to use faith in God to provide to the poor just to get out of helping the poor.
