Proverbs 4:23 says, “Above all else, guard your heart, for everything you do flows from it. Keep your mouth free of perversity; keep corrupt talk from your lips. Let your eyes look straight ahead; fix your gaze directly before you. Give careful thought to the paths for your feet and be steadfast in all your ways.” When Solomon refers to guarding the heart, he really means the inner core of a person, the thoughts, feelings, desires, will and choices that make that person who he or she is. The Bible tells us that our thoughts often dictate who we become. The mind of a person reflects who they really are, not simply their actions or words. This is why God examines the heart, not simply the outward appearance and what he or she appears to be.
