In the Bible, the meaning of “heart” in Hebrew refers to much more than just our physical organ or our fleeting emotions. The Hebrew word lev (or levav) represents the entire inner person—the center of your thoughts, your will, and your choices. While we often contrast the “head” and the “heart,” the biblical authors saw them as one, viewing the heart as the “control center” where we process information and make life-defining decisions.
More Than Just a Feeling
When we talk about the “heart” today, we usually mean our romantic feelings or a gut instinct. If you “follow your heart” in 21st-century culture, you are usually following your current mood. However, the ancient Israelites had a much broader definition. To them, the heart was the place where you think and make sense of the world. In the Old Testament, the heart is where wisdom is stored and where logic happens. It isn’t just the seat of your affections; it is the seat of your intellect.
In the Hebrew mind, you don’t just feel with your heart—you “think” with it. This is why the Bible often links the heart to understanding. If your heart is “hard,” it means your mind is closed to the truth. If your heart is “open,” it means you are willing to learn and grow. Understanding this shift in definition changes how we read almost every page of the Bible, moving us from a sentimental faith to a deep, integrated commitment of the whole person.
The Command Center of the Will
If the heart is the place of thought, it is also the place of action. The Bible describes the heart as the steering wheel of a person’s life. Every choice you make, from what you say to how you treat your neighbor, starts in the lev. This is why Proverbs 4:23 gives such a strong warning about protecting our inner world. What we allow to take root in our hearts eventually grows into the fruit of our outward behavior.
Proverbs 4:23 Guard your heart above all else, for it determines the course of your life.
Jesus built upon this Hebrew understanding during his ministry. He taught that the things that “defile” a person don’t come from the outside—like what we eat—but from the inside. He argued that murder, theft, and greed all start as tiny seeds in the heart. When we ask God to “change our hearts,” we aren’t just asking him to make us feel better; we are asking him to realign our will and our desires with his perfect plan.
A Heart Divided or Whole
A common theme throughout the Old Testament is the idea of a “divided heart.” Since the heart is the center of our loyalty and decision-making, having a divided heart means trying to live in two different worlds. It’s like a compass that can’t find North because it’s being pulled by two different magnets. The goal of the spiritual life, according to the Hebrew scriptures, is to have a “whole” or “undivided” heart that is completely devoted to God.
The most famous prayer in Jewish history, the Shema, commands people to love God with “all your heart.” This isn’t a call for an emotional high; it is a call for total allegiance. It means dedicating your thoughts, your plans, and your physical strength to the Lord. When our hearts are fractured by secret sins or competing priorities, we lose our spiritual direction. God’s desire is to take our “hearts of stone”—those parts of us that are cold and unresponsive—and turn them into “hearts of flesh” that can actually pulse with his love.
The Heart and Our Connection to Jesus
Ultimately, the biblical study of the heart leads us straight to Jesus. The prophets promised a day when God would write his laws directly on our hearts rather than on stone tablets. This promise came true through the Holy Spirit. Because of what Jesus did on the cross, we don’t have to struggle alone to “fix” our broken hearts. Instead, God offers us a brand-new heart through a relationship with his Son.
Ezekiel 36:26 And I will give you a new heart, and I will put a new spirit in you. I will take out your stony, stubborn heart and give you a tender, responsive heart.
When we invite Jesus into our lives, he begins a renovation project in our lev. He starts by cleaning out the thoughts and motives that don’t belong there and replaces them with his peace and wisdom. This transformation isn’t just about feeling happier; it’s about becoming a completely different person from the inside out. Your heart becomes the home where Christ dwells, guiding every thought and action as you follow him.
The Takeaway
The meaning of “heart” in Hebrew is the “all-encompassing center” of a human being, including the mind, the emotions, and the will. Understanding lev helps us realize that God wants more than just our Sunday mornings or our occasional good feelings; he wants the very core of who we are. When we surrender our hearts to him, we aren’t just giving him our emotions; we are giving him the steering wheel of our lives.
