The phrase “guard your heart” is often misunderstood in the Bible. So what does “guard your heart” actually mean?
The key Bible verse on guarding your heart is Proverbs 4:23 (NIV), “Above all else, guard your heart, for everything you do flows from it.” This is what we must do. But to accomplish this clear command to guard our hearts, we must first place Proverbs 4:23 in context.
