Answer
To better understand the causes and solutions for a hardened heart, itâs important to understand the broad biblical meaning of the word âheart.â The Bible considers the heart to be the hub of human personality, producing the things we would ordinarily ascribe to the âmind.â For example, Scripture informs us that grief (John 14:1); desires (Matthew 5:28); joy (Ephesians 5:19); understanding (Isaiah 6:10; Matthew 13:15); thoughts and reasoning (Genesis 6:5; Hebrews 4:12; Mark 2:8); and, most importantly, faith and belief (Hebrews 3:12; Romans 10:10; Mark 11:23) are all products of the heart. Also, Jesus tells us that the heart is a repository for good and evil and that what comes out of our mouth â good or bad â begins in the heart (Luke 6:43–45).
Considering this, itâs easy to see how a hardened heart can dull a personâs ability to perceive and understand. Anyoneâs heart can harden, even faithful Christiansâ. In fact, in Mark 8:17–19 we see Jesusâ own disciples suffering from this malady. The disciples were concerned with their meager bread supply, and it was clear that each of them had forgotten how Jesus had just fed thousands with only a few loaves. Questioning them as to the hardness of their hearts, Christ spells out for us the characteristics of this spiritual heart condition as an inability to see, understand, hear, and remember. Regarding this last criterion, too often we forget how God has blessed us and what He has done for us. Similar to the disciples in this instance or the Israelites wandering in the wilderness, when a new calamity arises in our lives, our hearts often fill with fear and concern. Sadly, this simply reveals to God the little faith we have in His promise to take care of us (Matthew 6:32–33; Philippians 4:19). We need to remember not only the many times God has graciously provided for us in our time of need, but also what He has told us: âNever will I leave you; never will I forsake youâ (Deuteronomy 31:6; Hebrews 13:5).
Sin causes hearts to grow hard, especially continual and unrepentant sin. Now we know that âif we confess our sins, [Jesus] is faithful and just and will forgive us our sinsâ (1 John 1:9). However, if we donât confess our sins, they have a cumulative and desensitizing effect on the conscience, making it difficult to even distinguish right from wrong. And this sinful and hardened heart is tantamount to the âseared conscienceâ Paul speaks of in 1 Timothy 4:1–2. Scripture makes it clear that if we relentlessly continue to engage in sin, there will come a time when God will give us over to our âdebased mindâ and let us have it our way. The apostle Paul writes about Godâs wrath of abandonment in his letter to the Romans where we see that godless and wicked âmen who suppress the truthâ are eventually given over to the sinful desires of their hardened hearts (Romans 1:18–24).
Pride will also cause our hearts to harden. The âpride of your heart has deceived you . . . you who say to yourself, âwho can bring me down to the groundâ . . . I will bring you down declares the LORDâ (Obadiah verses 3-4). Also, the root of Pharaohâs hard-heartedness was his pride and arrogance. Even in the face of tremendous proofs and witnessing Godâs powerful hand at work, Pharaohâs hardened heart caused him to deny the sovereignty of the one, true God. And when King Nebuchadnezzarâs âheart became arrogant and hardened with pride, he was deposed from his royal throne and stripped of his glory . . . until he acknowledged that the Most High God is sovereign over the kingdoms of men and sets over them anyone He wishesâ (Daniel 5:20–21). Accordingly, when weâre inclined to do it our way, thinking we can âgo it on our own,â it would be wise to recall what King Solomon taught us in Proverbs 14:12 and 16:25: âThere is a way that seems right to a man, but in the end it leads to death.â
So, what then is the antidote for a heart condition such as this? First and foremost, we have to recognize the effect that this spiritual disease has on us. And God will help us to see our heartâs condition when we ask Him: âSearch me O God, and know my heartâŚsee if there is any offensive way in me, and lead me in the way everlastingâ (Psalm 139:23–24). God can heal any heart once we recognize our disobedience and repent of our sins. But true repentance is more than simply a resolute feeling of steadfast determination. Repentance manifests itself in a changed life.
After repenting of our sins, hard hearts begin to be cured when we study Godâs Word. âHow can a young man keep his way pure? By living according to your word. I seek you with all my heart. . . . I have hidden your word in my heart that I might not sin against youâ (Psalm 119:9–11). The Bible is our manual for living as it is âGod-breathed and is useful for teaching, rebuking, correcting, and training in righteousnessâ (2 Timothy 3:16). If we are to live life to the fullest as God intended, we need to study and obey Godâs written Word, which not only keeps a heart soft and pure but allows us to be âblessedâ in whatever we do (Joshua 1:8; James 1:25).
Hearts can also become hardened when we suffer setbacks and disappointments in life. No one is immune to trials here on earth. Yet, just as steel is forged by a blacksmithâs hammer, so, too, can our faith be strengthened by the trials we encounter in the valleys of life. As Paul encouraged the Romans: âBut we also rejoice in our sufferings because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not disappoint us, because God has poured out His love into our hearts by the Holy Spirit, whom He has given usâ (Romans 5:3–5).
