(Proverbs 21:29 KJV) A wicked man hardeneth his face: but as for the upright, he directeth his way.
The KJV helps us understand what Solomon is saying and he is describing something we all go through even if we are not “wicked” (7563). The KJV says this guy “hardeneth” (5810) his face while the NASB says “shows a bold” face. The basic meaning of the word is to strengthen. For the evil around us it is putting on a happy face or a confident demeanor to hide the pain and confusion that is really eating them alive. It is the con man face. It is the face of the salesman who wants to sell you a time share.
For the righteous it may be the times when we lock a smile on our lips or work hard to stifle tears. It can be the ability to not show shock or disappointment. Remember how you worked to look overjoyed to get that diamond necklace for Christmas when you really wanted a new mixer.
So? As a believer our strong face is more based on our trust in God that our thespian skills. It may take a few moments to remind ourselves of why we are not to fear but the Holy Spirit will remind us if we give Him a chance.
