I wonder if you would agree that James’ teachings concentrate on the works that exemplify that justification. IMO, James was writing to Jews to encourage them to continue growing in this new Christian faith and to not turn back to the dogma and rituals of Judaism. James emphasizes that good actions will naturally flow from those who are filled with the Spirit and questions whether someone may or may not have a saving faith if the fruits of the Spirit cannot be seen, much as Paul describes.
James is exhorting, he is cheerleading, he is pushing, he is trying to wake (some) who are asleep in the Light.
And certainly there needs to be the fruit(s) of righteousness, shown in any believer's lifestyle.
But where this becomes theological trouble (Galatians 1:8 ) is when we begin to become legalists.
As long as we are doctrinally concluded that, "its not by our works of righteousness, but according to GOD"S MERCY that we are SAVED".
AS long as a believer, lives there, then preach works all you like, talk about water baptism if you must., but leave redemption to the CROSS where it was gained.
We work because we ARE saved, but not to try to BE saved or to stay saved.
After all, there is no work or commandment that can....... for sin atone.
We are BLOOD BOUGHT, we are not works bought, or commandment keeping bought, or confessing our sins, bought.
Salvation is God reconciling us to himself for eternity, based on the blood of Jesus.
We have no part in that, other then to receive it by faith.
