God's Word functions like a mirror that shows the true picture of who we are, just as surely as a looking glass shows a dirty face. James 1:22-25 contrasts the hearer only, who looks, walks away, and immediately forgets what he saw, with the one who looks into "the perfect law of liberty," continues in it, and does the work, and so is blessed in what he does, much like the man of Psalm 1 who delights and meditates in God's law. Hearing alone is self-deception, so the mirror must be used with the right attitude: meekness, laying aside filthiness and overflow of wickedness, and receiving the implanted word (James 1:19-21). Looking honestly reveals weakness, foolishness, and sin, and the proper response is to change rather than to feel self-satisfied. Three reasons to be doers are given: the Word begets and nourishes us (James 1:18), it prepares us as firstfruits who teach by example, and it keeps us from deceiving ourselves. Illustrations include thinking one can do calculus after watching the professor, or buying exercise equipment and never using it. The self-righteous Laodicean who looks in God's law, declares "I have no flaw," and forgets it is the mirror's warning. The remedy is to continue in the law and put out sin until every flaw is corrected.

The concept of the Law as a mirror reveals a profound truth about spiritual self-evaluation. James, the brother of Jesus, teaches that gazing into God's law, the perfect law of liberty, and becoming a faithful doer of the Word provides the only true and reliable reflection of our spiritual progress. Unlike distorted mirrors that deceive, such as those at amusement parks or on car side-views with warnings that objects are closer than they appear, God's law offers an undistorted image of our true condition. Yet, many prefer to measure their spiritual state by comparing themselves with others, a practice deemed unwise by the apostle Paul. This comparison distorts reality, much like human nature itself, which acts as a great deceiver by obscuring our own faults while magnifying those of others. The behaviors and faults we observe in others often serve as mirrors, reflecting our own shortcomings and sins that grieve God's Holy Spirit. When we see spiritual faults in others, we must use them as mirrors to examine our own progress, recognizing that the flaws we criticize may be closer to us than we perceive. God's law, therefore, stands as the ultimate mirror, urging us to confront and address the hidden sins within ourselves rather than focusing solely on the failings of those around us.

God's law and Word serve as the standard against which we measure ourselves, and a glance in the mirror is not enough (James 1:24). The Greek word for examine, dokimazo, means to test, discern, and prove, implying scrutiny, investigation, searching, and correcting. Paul commands self-examination before Passover and calls believers to put themselves on trial, judging themselves so that God need not judge them (I Corinthians 11:28-32). Those who govern themselves by God's Word with outgoing concern for others do not have to be governed, which is what it means to be not under the law (Galatians 5:18). There is no judgment when the law is kept, just as a cop never ticket a driver for observing the speed limit. Honest self-examination requires diligence and brutal honesty, because human nature flatters itself, and lying to ourselves breaks the ninth commandment. Passion becomes a false standard, and a man effectively worships himself. David could not see his fault until Nathan said, "You are the man." Job did not grasp the gulf between himself and God until God questioned him. Peter, seeing Christ's power, saw himself as a sinful man. Each saw himself truly only in relation to God, and each was changed. God will give those He commands to examine themselves the ability to see themselves as they are.
