The Secret to Loving God and Others: What Is the Greatest Commandment?

Why Was This Question Being Asked?

The Jewish teachers in Jesus’s day counted 613 individual commandments in the law of Moses. Debates about which one stood above the rest were common, serious, and sometimes heated. When a legal expert asked Jesus to name the greatest, it was not a simple Sunday school question — it was a theological challenge.

Jesus answered by quoting from Deuteronomy 6:5, a passage so central to Jewish daily life that devout people recited it every morning and evening. His audience would have recognized it immediately. He was not inventing a new rule; he was pointing to what had always been at the center.

Then he added a second command from Leviticus 19:18 — love your neighbor as yourself — and declared it inseparable from the first. In doing so, he showed that genuine love for God will always spill outward toward other people. You cannot have one without the other taking root.

What Does ‘All Your Heart, Soul, and Mind’ Actually Mean?

In the ancient world, the heart was not just the seat of emotion — it was the center of your will, your decisions, your deepest motivations. To love God with all your heart means your choices, your loyalties, and your desires are oriented toward him.

The soul, in Hebrew thought, points to your whole living self — the breath of life in you, your very existence. Loving God with your soul is about offering your entire being, not just a dedicated Sunday-morning portion of yourself.

The mind was a word Jesus added when translating this commandment for his Greek-speaking audience, and it is a meaningful addition. Your thoughts, your reasoning, your intellectual life — these are not separate from faith. Honest doubt, hard questions, and careful reading of Scripture are all part of loving God with your mind.

Taken together, these three — heart, soul, and mind — are a way of saying: hold nothing back. Not a partial commitment made when life is comfortable. The call is to a whole-person love, offered even in seasons when it costs something.

Who Is Your Neighbor?

That follow-up question was actually asked, too. In Luke 10:29, someone pressed Jesus on exactly this point, and Jesus responded with the parable of the Good Samaritan. The neighbor was not someone from the same background, the same town, or the same religion. The neighbor was the one who showed mercy.

Your neighbor, by Jesus’s definition, is whoever is in front of you and in need. The colleague who is struggling quietly. The stranger across a cultural divide. The person you would rather not have to think about. The command does not grant you the luxury of a narrow list.

This is not meant to overwhelm you. It is meant to expand your field of vision, slowly and steadily, as love grows. You do not have to fix the world today. You do have to pay attention to the person in front of you today.

What Does ‘Love Your Neighbor as Yourself’ Assume?

The command assumes that you have some basic care for your own wellbeing — that you feed yourself, rest, seek help when you are hurting. That self-regard is the starting measure for how you treat others. You are meant to extend to your neighbor the same practical concern you extend to yourself.

This is worth sitting with if you tend toward self-neglect or constant self-criticism. The command is not asking you to pour from an empty cup indefinitely. Caring for your own health — physical, emotional, spiritual — is not selfishness. It is the baseline the command points to.

If you are carrying grief, anxiety, or chronic struggle right now, please know: reaching out for professional support, whether a counselor, a doctor, or a trusted mentor, belongs alongside prayer. God works through both, and seeking help is not a sign of weak faith. It is often the wisest form of self-care the command describes.

How These Two Commands Hold Everything Together

Jesus said in Matthew 22:40 that all the law and the prophets depend on these two commands. That is a staggering claim. He is not suggesting the other commandments are unimportant — he is saying that if you understand love for God and love for people, you have the key that opens all the others.

Think of it this way: the Ten Commandments (Exodus 20) divide naturally into obligations toward God and obligations toward other people. The teachings of the prophets — justice for the poor, care for the vulnerable, honesty in community — are all expressions of neighbor-love made concrete. The greatest commandment is not a replacement for specific ethics; it is the root from which they grow.

The apostle Paul makes a similar move in Romans 13:9-10, and John returns to the theme repeatedly in 1 John, insisting that love for God and love for others cannot be separated. This thread runs through the whole New Testament because Jesus put it at the center.

Living the Greatest Commandment in Ordinary Days

The greatest commandment is not primarily a feeling to chase. It is a direction to face. Some mornings you will wake up and feel deeply connected to God. Other mornings you will feel nothing, and love will look more like showing up anyway — opening your Bible, saying a short honest prayer, choosing patience with someone who is difficult.

Practically, loving God with your mind might mean spending ten minutes in Scripture each morning, not to check a box, but to listen. Loving God with your heart might mean bringing your actual worries and joys to him in prayer rather than a polished version of yourself. Loving your neighbor today might be as small as paying full attention in a conversation instead of half-listening while you look at your phone.

Small, repeated acts of love are not small in God’s economy. They are the daily practice of the greatest commandment. Over time, they shape you — quietly, steadily — into someone who loves more freely and more genuinely than you do right now.

Start where you are. You do not need to feel spiritually advanced to obey this command. You need only to be willing. That willingness, offered honestly to God, is itself a form of love.

A Place to Begin If This Is New to You

If you are a seeker or someone who is new to faith, the greatest commandment is a remarkably good place to plant your feet. It does not ask you to master a theological system before you can start. It asks you to love — imperfectly, incrementally, with whatever you have today.

You might begin by simply telling God honestly where you are. Not a formal prayer — just a few plain sentences. Something like: I am not sure what I believe yet, but I want to know you. Help me understand what love like this looks like. That is enough to start.

The rest unfolds from there. As you read the Gospels — starting with the book of Mark or John is a natural entry point — you will find that Jesus consistently pulls everything back to this center. Love God. Love people. Everything else is commentary on these two commands.
