In simplicity— Plain-heartedness; not only meaning well on the whole, but declining an over-artful way of prosecuting a good end. What is meant by fleshly wisdom, may be seen, ch. 2 Corinthians 2:5. St. Paul's working with his own hands for his maintenance among the Corinthians, (Acts 18:3. 1 Corinthians 9:15.) which he did not every where, must be a convincing proof of what he observes in the late clause of this verse.
