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.”
Augustine on Writing
“I freely confess accordingly that I endeavor to be one of those who write, because they make some progress and who by means of writing, make further progress.”
