James 1:22-25 But be you doers of the word, and not hearers only, deceiving your own selves. For if any be a hearer of the word, and not a doer, he is like unto a man beholding his natural face in a glass: For he behold himself, and go his way, and straightway forget what manner of man he was. But whoso look into the perfect law of liberty, and continue therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
Those who ‘do’ the Word of God are those who live in continued obedience to its commands and who doesn’t just ‘hear’ the Word and deceive themselves with their own opinion and false reasoning or interpretation of what they think God actually meant.
He sees his blemishes and imperfections and is moved by what he sees. As long as he sees his deformities, spots, and ugliness he tries to do something about them. But when he turns away from the mirror, he forgets and his imperfections no longer bother him. So it is with the Bible. As long as one studies it, he sees himself as he really is and constantly seeks to improve himself and conform to its teaching. If he gets away from the Bible, a man soon forgets the real picture of himself, “what manner of man he was”.
The perfect law of liberty does not refer to the law of Moses, but to the new covenant, the only perfect law (Heb. 8:6). The law of Moses was imperfect and faulty (Heb. 7:12, 18-19, 22; 8:6-7).
The idea is taken from women spending much time in the mirror decorating themselves to the greatest advantage, not leaving one hair or the smallest ornament out of place. Thus, if one will be as careful to take every advantage of the Word of God to keep his soul saved and his life conformed to the gospel, he will “be blessed in his deed.”
