Charles H. Spurgeon on Psalms 119:38

Stablish thy word unto thy servant. Why doth David pray thus, "Stablish thy word to me; "since God's word is most certain and so stable in itself that it cannot be more so? (2 Peter 1:19). "We have a more sure, "or a more stable, "word of prophecy, "as the word signifies. How can the word be more stable than it is? I answer, it is sure in regard of God from whom it comes, and in itself. In regard of the things propounded it cannot be more or less stable, it cannot be fast and loose: but in regard of us, it may be more or less established. And that two ways,

1. By a dread of his displeasure.

2. Desire of his favour.

3. Regard for his excellencies.

4. Submission to his will.

5. Gratitude for his benefits.

6. Conscientious obedience to his commands. Charles Buck.
