Proverbs 16:2

All the ways of a man are clean in his own eyes; but the LORD weigheth the spirits.

All human ways can appear clean and right to the person who walks in them, but the Lord weighs the inner spirit, judging character and motives as good or evil rather than accepting human self-approval. That weighing searches the depths of the heart, reading every motive, purpose, thought and secret of the soul, even what is deliberately hidden, so outward correctness cannot conceal what is within. No sense of innocence, plausible words, or favorable self-judgment can make defiled thoughts or corrupt aims clean, for God knows the secret motives and sees the harm done, and His estimate alone is true. He weighs both motives and actions together, including their effects, testing each character by His holy and unchanging law whose record will be revealed at the judgment. The verse therefore warns against self-confidence and calls for humble, honest examination of heart, plans and judgment, measuring life by God's law, confessing and forsaking wrong, and trusting in Christ's merits to supply what personal obedience lacks.

The Lord Weighs Motives

All the ways of a person may appear clean and right in his own eyes, but the Lord weighs the spirits, examining inner character and motives, whether good or evil, rather than accepting human self-assessment. His weighing reaches beyond outward conduct to the heart, for He reads every motive, purpose, and thought behind what is done. He judges the spirit behind actions truly, so a person's own judgment that all his conduct is right does not settle the matter.

To weigh the spirits is to read every motive in the depths of the heart and every secret of the soul, including motives and plans that people try to hide. No outward self-approval can hide what is within, for hidden motives and secrets are open before Him. His assessment alone is true, and what is now hidden will be revealed when actions are judged by what is recorded in the books.

A person's own sense of innocence does not determine whether the heart is right before God, and human self-assessment does not determine whether a course is right. Plausible words and self-approval do not make defiled thoughts or corrupt attentions clean, for God knows the secret motives and inner purposes. He also sees the harm caused by such a course, while the one who excuses himself regards his own conduct as proper.

The Lord weighs both motives and actions in determining character, for He knows every thought and motive and assesses what people do. That weighing includes the effects of deeds, so character and actions together are brought into judgment. Each character is tested against His holy, unchanging law, and the comparison determines judgment, with actions to be revealed at judgment by what is recorded in the books.

Call to Humble Examination

The verse warns against self-confidence, for a person may judge all his own conduct to be right while being mistaken, but the Lord weighs the inner spirit, examining character and motives whether good or evil. It therefore calls for humility instead of trusting one's own judgment, and for honest self-examination of the heart, of plans, and of judgment itself. That examination includes confessing errors when wrong actions have looked right, and diligently improving the faculties God has given. Receiving more light alone is not enough, for the soul must surrender to God so that His grace makes the light already received a living principle of action. Self-confidence can lead even one who has great light to take crooked paths, and to draw others after that example. Deeds that obstruct the work of salvation are weighed by God, who reads every thought, motive, and purpose and assesses character and actions including the effects of deeds, and such deeds are found wanting. Each character is tested against God's holy, unchanging law, and the comparison determines the person's judgment, rather than any self-assessment. The verse therefore calls people to examine their motives and actions by that law, to repent of transgression, and to rely on Christ's merits to supply what their own obedience lacks.
