Writers in the Bible often speak of adultery as a metaphor for people who say they love God but do things that God hates. (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/tw/dict/bible/kt/godly]])
James asks many questions because he wants his readers to think about how they are living. He wants to correct and teach them. (See: [[rc://en/ta/man/jit/figs-rquestion]])
This word probably usually refers to people who are not proud. James uses the word here to refer to people who are not proud and who also trust in Jesus and obey him.
