Why the question?
The Jehovah's witnesses accept that real Faith inspires works which is the point James makes. A pretense of Faith is shown to be dead because it would not inspire works.
Preaching just becomes an annnoying thing accept to those that truly believe the life-saving message from God they are bringing to people.
The 2 criminals next to Jesus certainly did have works if you read the story.
luke 23:39One of the criminals who hung there hurled insults at him: "Aren't you the Christ? Save yourself and us!"
and the one Jesus promised paradise to???
40 But the other criminal rebuked him. "Don't you fear God," he said, "since you are under the same sentence? 41 We are punished justly, for we are getting what our deeds deserve. But this man has done nothing wrong."
42 Then he said, "Jesus, remember me when you come into your kingdom. [f] "
The other criminal rebuked the one insulting Jesus. His next words show he fully believed Jesus was innocent and in the kingdom promise.
I don't know how you can say he hadn't done works? his faith in Jesus and God's kingdom is there for all to see. Maybe it is your definition of works that is skewed?
