Here we have a prayer for conviction. The psalmist cries out for God to build a desire and sense of divine necessity. The initial mention here of teaching uses a Hebrew word that paints a picture of pouring out something, to make an obvious splash that changes the color of the ground. The psalmist asks that God make things more obvious to him. For his part, the writer promises that the last thing anyone will see of him will be walking that path. Indeed, he commits himself to investing his whole being in making certain that at least this one person shall consistently demonstrate what God says He wants for us.
Indeed, the heart-led life is such a delight that the psalmist asks he never get lost and wander from it. He prays that his inclinations are bent toward the divine revelation of what life is supposed to be like on this earth, and not to get lost in any desire for plundering from others.
How much better is life when we find it painful to look on things that drain the moral fullness of the heart! Let us fully experience the joy of walking God’s path for us. We should long for that living truth to grow up and consume our being so that we lack nothing in our commitment to serving Him.
If there is one thing the psalmist rightly fears, it is moral disgrace. He begs for the Lord to evaluate his commitment and reveal the weaknesses, because correction from God is better than reward from any other source. Indeed, he longs passionately for a clear grasp on reality as God defines it. The breath of life is the revelation of the moral character of God.
