The ability to distinguish what is right from what is wrong, is a unique gift from God to man. It is commonly called conscience, while some people call it their inner voice. The Bible refers to it simply as the heart. Our conscience nudges us, our inner voice speaks to us, our heart reminds us to do what is good, to speak the truth, to act justly, to work honestly.
Of course, we have that heart which works tirelessly throughout our existence on earth. If it were to stop beating, we would be no more. But the heart that the Bible mentions is not like it. It is not a robot or a machine that runs on its own. This heart is in constant touch with God. It helps us to establish communication with God. No wonder that God has written his laws on our hearts so that they are forever available for our reference! (Jeremiah 31:33)
Our heart gives us lessons in morality and ethics. If we do something wrong, if we hurt someone, if we miss the opportunity to do something good, the heart reminds us of it. We then feel sorry, repent of our actions, have a feeling of remorse, all because we have a heart within us.
David prays, “Create in me a pure heart, O God, and renew a steadfast spirit within me.” (Psalm 51:10) The Bible advises us, “Above all else, guard your heart, for everything you do flows from it.” (Proverbs 4:2) And God says to us, “You will find me when you seek me with all your heart.” (Jeremiah 29:13)
Our physical heart is crucial for the proper functioning of our entire body. When we hear its steady beat, we feel reassured. Our hidden heart is crucial for our spiritual well-being. When we hear it speak, we must listen and take heed.
