Commenting on Ecclesiastes 12:13, Loyal Young writes:

The true interest of man is to fear God, and keep his commandments. This settles all the questions of ancient philosophy about “the chief good.” This settles the anxious inquiries of the present day as to duty. Piety and obedience are the whole duty and interest of man. Let. us reverence our Heavenly Father, and entrust all our interests into his hands. He watches over our path and our pillow, and we are safe under the covert of his wings. Let us fear God by genuine penitence, and seeking forgiveness through the blood of Jesus. His law is for our guide—let us obey it. It is the transcript of his holy will. In a child nothing is so beautiful as cheerful obedience. The parent smiles with joyful approval. And God smiles approvingly on all his obedient children. Religion begins in the fear of the Lord, and it matures into obedience. The life of the future harvest is in the seed cast into the bosom of the earth. The rain-drop moistens it—the sun-beam warms it into life. It grows, matures, ripens into a harvest. So, in beautiful order, under the genial rays of the Sun of righteousness, the implanted fear of the Lord ripens into a golden harvest of duty. Faith overcomes the world—works righteousness—stops the mouths of lions—turns to flight the armies of the aliens.
