Vs. 70 — Their heart is as fat as grease, But I delight in Your law.

William Fenner:

“Their heart is as fat as grease; but I delight in thy law;” as if he should say, My heart is a lean heart, a hungry heart, my soul loveth and rejoiceth in thy word. I have nothing else to fill it but thy word, and the comforts I have from it; but their hearts are fat hearts; fat with the world, fat with lust; they hate the word. As a full stomach loatheth meat and cannot digest it; so wicked men hate the word, it will not go down with them, it will not gratify their lusts.

Prayer:

Father, I fear that my heart may also become as fat as grease. Do not let my affections wander from Thee. Keep my heart tender, hungry, and meek for Thy meat and Thy bread, and not for the luxuries of this life. Grant me a hunger for Thy Law that will not be quenched; a thirst for the springs of eternity life that will not dry up. Purge the fat from my soul so that I will not become complacent towards Thee, and do not let me lose sight of my desperate dependence upon the Savior–Jesus Christ. Amen.
