Obey the word of God" or "Obey God's message to you."
## deceiving your own selves ##
"deceiving yourselves" or "fooling yourselves"
## For if anyone hears the word and does not do it, he is like a man examining his natural face in a mirror. ##
James makes a comparison between a person who hears God word and does not obey it to a person who looks in the mirror then forgets what he looks like. (See: [[rc://en/ta/man/translate/figs-simile]])
## examining his natural face...and soon forgets ##
the man looking at his face and soon forgetting what he saw is the like the man who hears the Word of God and forgets what he heard.
