Albert Barnes Commentary Psalms 25:9

"The meek will he guide in justice; And the meek will he teach his way." — Psalms 25:9 (ASV)

The meek will he guide - The humble, the teachable, the prayerful, the gentle of spirit—those who are willing to learn. A proud person who supposes that he already knows enough cannot be taught; a haughty person who has no respect for others, cannot learn from them; a person who is willing to believe nothing cannot be instructed. The first requisite, therefore, in the work of religion, as in respect to all kinds of knowledge, is a meek and docile spirit. See Matthew 18:3.

In judgment - In a right judgment or estimate of things. It is not merely in the administration of justice, or in doing right, but it is in judging of truth; of duty; of the value of objects; of the right way to live; of all upon which the mind can be called to exercise judgment, or to come to a decision.

And the meek will he teach his way - The way in which He would have them to go. The methods by which God does this are:

1. By His word or law:
   1. laying down in it the principles which are to guide human conduct, and
   2. in numerous cases furnishing specific rules for directing our conduct in the relations of life;
2. By His Spirit:
   1. disposing the mind to candor,
   2. enlightening it to see the truth, and
   3. making it honest and sincere in its inquiries;
3. By His providence—often indicating, in an unexpected manner, to those who are sincere in their inquiries after truth and duty, what He would have them to do; and
4. By the advice and counsel of those who have experience—the aged and the wise—those who have themselves been placed in similar circumstances, or who have passed through the same perplexities and embarrassments.

By all these methods a person who goes to God in humble prayer, and with a proper sense of dependence, may trust that he will be guided rightly; and it is not probable that a case could occur in which one who honestly seeks for guidance by these helps might not feel assured that God would lead him rightly. Having used these means, a person may feel assured that God will not leave him to error.
