Calvin points out in his commentary on Psalm 18 (vv. 21 – 24) that “whoever, therefore, would desire to persevere in uprightness and integrity of life, let them learn to exercise themselves daily in the study of the Word of God; for, whenever a man despises or neglects instruction, he easily falls into carelessness and stupidity, and all fear of God vanishes from his mind.”
From Psalm 17
“When clothed in righteousness at last,
Thy glorious face I see,
When all this weary night is past,
And I awake with Thee,
To view the glories that abide,
Then – how I shall be satisfied”
