Question: "What does it mean to guard your heart?"
Answer: Proverbs 4:23–26 instructs believers to, “above all else, guard your heart, for everything you do flows from it. Keep your mouth free of perversity; keep corrupt talk far 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/she is. The Bible tells us that our thoughts often dictate who we become (Proverbs 23:7; 27:19). The mind of a man reflects who he really is, not simply his actions or words. That is why God examines the heart of a man, not simply his outward appearance and what he appears to be (1 Samuel 16:7).
Just as there are many diseases and disorders that can affect the physical heart, there are many ailments of the spiritual heart that can impair growth and development as a believer. Atherosclerosis is a hardening of the arteries due to accumulated cholesterol plaques and scarring in the artery walls. Hardening of the spiritual heart can also occur. Hardening of the heart occurs when we are presented with God’s truth, and we refuse to acknowledge or accept it.
Although Egypt was stricken with one calamity after another when the pharaoh refused to release the Israelites from their bondage, he hardened his heart against the truth that God Almighty intended to deliver His people from Egypt (Exodus 7:22; 8:32; 9:34). In Psalm 95:7–8, King David pleaded with his people not to harden their hearts in rebellion against God as they did in the wilderness. There are many things that can harden the heart and lead a person to deny God, and just like cholesterol blocks blood flow, they keep a believer from having a free flow of God’s peace and blessings derived from obedience. Guarding against a rebellious spirit and cultivating a spirit of submissive obedience to God’s Word, therefore, is the first step in guarding the heart.
Heart murmurs are abnormal flow patterns due to faulty heart valves. Heart valves act as doors to prevent the backward flow of blood into the heart. Spiritual heart murmurs occur when believers engage in complaining, gossip, disputes, and contention. Believers are instructed many times to avoid grumbling, murmuring, and complaining (Exodus 16:3; John 6:43; Philippians 2:14). By engaging in these activities, believers shift their focus away from the plans, purposes, and past blessings of God to the things of the world. God sees this as a lack of faith, and without faith, it is impossible to please God (Hebrews 11:6). Instead, Christians are instructed to strive for contentment in all things, trusting in God to provide what is needed in His good time (Hebrews 13:5). Guarding against a complaining spirit and cultivating a spirit of gratitude and trust is the second step toward guarding the heart.
Congestive heart failure is an inability of the heart to successfully pump blood through the body due to weaknesses within its walls. Congestive heart failure can result from hypertension (high blood pressure), myocardial infarctions (heart attacks), and abnormal enlargement of the heart. The spiritual equivalents are anger, giving in to temptation, and pride. Anger acts like a poison on the body, both physically and spiritually, and makes a believer more vulnerable to the temptation to hurt others with our actions and words. Ephesians 4:31–32 instructs, “Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you.”
Every Christian is locked in a constant, intense war with demonic forces. Many of us become so intent on fighting the external spiritual war that we forget that much of our battle is not with external forces, but with our own mind and thoughts. James 1:14–16 tells us, “Each person is tempted when they are dragged away by their own evil desire and enticed. Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death. Don’t be deceived, my dear brothers and sisters.” Sin always begins in the mind. A sinner must first conceive and dwell on the sinful action before he actually carries it out. The first line of defense, therefore, must be to refuse to even contemplate a wrongful action. The apostle Paul tells us to take every thought captive, so that it conforms to the will of God (2 Corinthians 10:3–5).
Proverbs 16:18 tells us that pride leads to destruction. Proverbs 16:5, says, “Everyone proud in heart is an abomination to the Lord.” Pride was the first great sin of Satan, when he thought that he could be like God and incited one third of the angels to attempt a coup in heaven (Ezekiel 28:17). For this reason, Satan was cast from heaven. Satan also tempted Eve in the Garden of Eden by appealing to her ego. He said, “For God knows that when you eat from [the forbidden tree] your eyes will be opened, and you will be like God, knowing good and evil.” Eve desired to be as wise as God, so she capitulated to Satan’s advice to eat of the fruit of the tree. Pride was, therefore, the downfall of man, as well. Satan did not want man to obey God but to become his own god—determining for himself reality, meaning, and ethics. This satanic philosophy is the foundational philosophy of sorcery, secular humanism, and New Age mysticism.
Avoiding anger, pride, and temptation are also critical elements of guarding the heart. The apostle Paul instructs us, “Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things” (Philippians 4:8). Dwelling on these things will help to build a guard fence around our hearts.
