If men satisfy the flesh then the inward man still remains hungry. ‘Instead of yielding solid delight, they only proved vexatious, because the pleasure was soon over, and left a thirst for more. At most and best only the outward senses were fed, the mind not at all improved, nor the heart made better, and much less contented’ (Gill).
If all is without profit, then all motivation for life is gone. Why bother to strive to achieve anything? Does the Lord really wish us to arrive at this conclusion? Yes, for there is nothing better than that a man should see the vanity of his life and begin calling upon the name of the Lord. Conversion is a crisis experience, but it is often preceded by the awful realisation that there is nothing at all in this world that can satisfy our souls.
