"I have read in Plato and Cicero sayings that are wise and very beautiful; but I have never read in either of them: Come unto me all ye that labor and are heavy laden"

This quote by Saint Augustine is a tip that although the wisdom of Plato and Cicero is valuable, it is inadequate to supply us with the spiritual guidance we require. Augustine is suggesting that the teachings of these 2 excellent thinkers are inadequate to supply us with the comfort and solace we seek in times of distress. He is explaining that the words of Jesus, "Come unto me all ye that labor and are heavy packed", are the only words that can genuinely supply us with the peace and hope we require in times of difficulty. Augustine is highlighting the value of turning to Jesus for spiritual guidance and comfort, rather than relying solely on the knowledge of philosophers. He is reminding us that Jesus is the only one who can truly supply us with the strength and nerve we need to face our struggles.
