Psalms 119:11

"Thy words have I hid within my heart, that I may not sin against Thee" (ver. 11). He at once sought the Divine aid, lest the words of God might be hidden without fruit in his heart, unless works of righteousness followed. For after saying this, he added, "Blessed art Thou, O Lord, teach me Thy righteousnesses" (ver. 12). "Teach me," he saith, as they learn who do them; not as they who merely remember them, that they may have somewhat to speak of. Why then doth he say, "Teach me Thy righteousnesses," save because he wisheth to learn them by deeds, not by speaking or retaining them in his memory? Since then, as it is read in another Psalm, "He shall give blessing, who gave the law;" therefore, "Blessed art Thou, O Lord," he saith, "O teach me Thy righteousness." For because I have hidden Thy words in my heart, that I may not sin against Thee, Thou hast given a law; give also the blessing of Thy grace, that by doing right I may learn what Thou by teaching hast commanded. ...

Thy word have I hid in mine heart,....

We must carefully treasure up the word of God, declare it to others, meditate on it, and heartily delight in it; and then by His grace we shall act according to it.

When a godly man sues for a favour from God he should carefully use every means for obtaining it, and accordingly, as the Psalmist had asked to be preserved from wandering, he here shows us the holy precaution which he had taken to prevent his falling into sin. "Thy word have I hid in mine heart." His heart would be kept by the word because he kept the word in his heart.

When a godly man sues for a favour from God he should carefully use every means for obtaining it, and accordingly, as the Psalmist had asked to be preserved from wandering, he here shows us the holy precaution which he had taken to prevent his falling into sin. "Thy word have I hid in mine heart." His heart would be kept by the word because he kept the word in his heart. All that he had of the word written, and all that had been revealed to him by the voice of God,—all, without exception, he had stored away in his affections, as a treasure to be preserved in a casket, or as a choice seed to be buried in a fruitful soil: what soil more fruitful than a renewed heart, wholly seeking the Lord? The word was God's own, and therefore precious to God's servant. He did not wear a text on his heart as a charm, but he hid it in his heart as a rule. He laid it up in the place of love and life, and it filled the chamber with sweetness and light. We must in this imitate David, copying his heart work as well as his outward character. First, we must mind that what we believe is truly God's word; that being done, we must hide or treasure it each man for himself; and we must see that this is done, not as a mere feat of the memory, but as the joyful act of the affections. "That I might not sin against thee." Here was the object aimed at. As one has well said,—Here is the best thing—"thy word;" hidden in the best place,—"in my heart;" for the best of purposes,—"that I might not sin against thee." This was done by the Psalmist with personal care, as a man carefully hides away his money when he fears thieves,—in this case the thief dreaded was sin. Sinning "against God" is the believer's view of moral evil; other men care only when they offend against men.
