Fear of God

Happy is the man that feareth alway: but he that hardeneth his heart shall fall into mischief (Proverbs 28:14).

A man who fears God remains happy always but one who hardens his heart without fear of God shall fall into mischief. Mischief befalls every one, even a child of God, if he hardens his heart due to deceitfulness of sin.
