The reason I like these Bible verses so much is that they are straightforward & thus require no need for complex thinking or interpretation, which I find frustrating & difficult to do. Choosing to live with God as your Leader is not intended to cause confusion with rules, but rather peace with guidance.
Verse 23 reveals a terrific truth & after that comes the ending of the next verse I find too often difficult to obey but ideally prefer to adhere to.
Above all else, guard your heart, for everything you do flows from it. 24b Keep corrupt talk far from your lips.
Proverbs 4:23 & 24b
