(Matthew 15: 8,9) This people honors me with their lips, but their hearts are far from me, because out of the heart come evil thoughts, murders, adulterers, fornicators, thefts, false testimonies, blasphemies. These are the ones that contaminate man, but eating with unwashed hands does not contaminate man.
PROVERBS 4:23
Above all else, guard your heart; because of life mana, with all diligence guard your heart, because from it spring the springs of life, take care of your mind more than anything in the world, because it is a source of life.
When Solomon was referring to keeping his heart, he really wanted to say the inner essence of a person, refers to the thoughts, feelings, desires, will and decisions that a person makes. The bible tells me that our thoughts often determine what we become. The mind of a man reflects what he really is, not only by his actions or words. It is because God examines a man's heart, not simply his outward appearance and what he appears to be.
Just as there are many diseases and disorders that can affect the physical heart, there are many Spiritual ailments that can affect growth and development as a believer. The hardening of the heart occurs when the truth of God is presented to us, and we refuse to acknowledge or accept it.
Egypt was afflicted when Pharaoh refused to free the Israelites from their bondage, he hardened his heart against the truth of God. King David begged him not to harden his heart any more.
Spiritual heart murmurs occur when the believer participates in complaints, gossip, conflicts and quarrels.
Keep the heart is to protect us from a Spirit of complaints and cultivate a Spirit of gratitude and trust, remaining in this case will help us build a fence of protection around our heart.
