(Proverbs 28:14 KJV) Happy is the man that feareth alway: but he that hardeneth his heart shall fall into mischief.
A bit of insecurity can make your day. I think I am a pretty good driver. It is easy for me to fall into a sense of security because I know I won’t do anything stupid. That is a stupid thing to do. I need to have a healthy fear of the crazy drivers around me. That means driving defensively. It means watching your mirrors and keeping extra distance. It means a healthy fear that keeps you alert.
Lack of fear brings “calamity” (7463a) according to the NASB and “mischief” (7451) according to the KJV. The root word for this is evil and that is the most common translation in both. This is the fear that keeps you off the thin ice when skating. It is the fear that makes you alert in rattlesnake country. It is the fear that makes you look both ways before you cross a street. It is the fear that makes you live without terror.
So? Go ahead, be afraid. It may make your day.
