Ecclesiastes 8

There can be no question that the Bible teachers that godly wisdom brings God's favor and peace to a life. But the beginning of Ecclesiastes 8 points out two more benefits of pursuing and possessing wisdom. It "brightens their appearance." Godly wise people radiate God's joy because his wisdom has permeated their hearts.
It also softens his harsh countenance. Learning can lead to great confidence which can cause unrealistic expectation being projected on to other people. The one who adds godly wisdom "softens his harsh countenance." A soft spoken attitude can be more valuable than a head full of knowledge in almost any conflict.
