How to Love God: The Greatest Commandment Explained
Short answer: To love God is to respond to the God who has already spoken and already loved. In Mark 12:28-34 a scribe asks Jesus which commandment is greatest, and Jesus answers by joining Deuteronomy 6:4-5 to Leviticus 19:18: love God with all your heart, soul, mind, and strength, and love your neighbor as yourself. Jesus is not giving a technique for producing warm feelings. He is describing a whole life oriented toward God—trust, obedience, worship, and mercy—because God is one, and because he loved us first. Love for God is commanded, which means it is possible for ordinary people, and it is measured less by intensity of emotion than by the direction of a life.
Why the scribe asked which commandment was greatest
The question in Mark 12:28 did not come out of thin air. Jesus had just silenced the Sadducees on the resurrection, and one of the scribes heard the exchange and recognized that Jesus had answered well. His question was a real debate question among the teachers of the law. The rabbis counted 613 commandments in the Law, and they discussed which were weighty and which were light. Some might say the Sabbath, others circumcision, others the commands about sacrifice. The scribe wanted to know how Jesus ranked them.
It is worth noticing that the scribe's question is honest rather than hostile. Mark says he heard them questioning together and knew that Jesus had answered them well. He is not setting a trap as the Pharisees and Herodians had done earlier in the chapter. He is a student of Scripture asking a teacher of Scripture a serious question. That matters for how we read the answer: Jesus is not dodging a trap here, he is giving instruction to someone who wants to learn.
The setting is the temple courts during the final week of Jesus' ministry. Tensions are high, and every answer Jesus gives is being weighed. In that atmosphere, the question about the greatest commandment is not academic trivia. It is a question about the shape of faithful life. If someone can only keep one thing in view, what should it be? Jesus' answer reframes the whole discussion: the greatest commandment is not a ritual but a relationship, not a ceremony but a love that takes up the entire person.
We should also notice that Jesus does not dismiss the other commandments. He does not say the rest do not matter. He says this one is greatest, and the second is like it. The commandments hang together, and the greatest one gives the others their proper place. When love for God is central, the rest of the law is no longer a random list of rules but a coherent way of living before the God who made us.
Hear, Israel: the foundation Jesus quotes
Jesus begins his answer with the Shema, the daily confession of Israel drawn from Deuteronomy 6:4-5. The supplied text reads, Deuteronomy 6:4-5 says, "Hear, Israel: Yahweh is our God. Yahweh is one." Before there is a command to love, there is a declaration about who God is. The command rests on the identity of God. Israel is not asked to work up affection for an unknown deity; they are called to respond to the God who rescued them from Egypt and made a covenant with them.
The word hear is not a request for information. In Hebrew thought, to hear is to listen with the intent to obey. It is the same posture as a servant before a master or a child before a parent. Jesus quotes this word because love for God begins with attention. We cannot love a God we have not listened to. The first act of love is to stop and hear what God has said about himself in his word.
The confession that Yahweh is one was a direct challenge to the surrounding nations, who worshiped many gods. Israel was surrounded by people who divided their loyalty among Baal, Asherah, Molech, and a host of others. The Shema says there is one God, and he will not be one among many. He is not a tribal deity to be added to a collection. He is the only God, and he deserves the whole heart, not a fraction of it.
That is why the command that follows is so total. If God is one, then love for him cannot be divided. It cannot be one compartment among many. It cannot be Sunday morning only. The oneness of God shapes the wholeness of our love. Jesus takes this ancient confession and places it at the center of his answer, showing that the greatest commandment is rooted in the very nature of God himself.
Heart, soul, mind, and strength: what wholehearted love means
The command in Mark 12:30 lists four spheres: heart, soul, mind, and strength. These are not four separate duties, as if we could love God with the mind but not the heart. They are overlapping ways of saying the whole person. The heart in Scripture is the center of will and decision, not merely emotion. The soul is the life God breathed into us. The mind is our reasoning and attention. Strength is our bodily energy and capacity. Together they say: hold nothing back.
Loving God with the mind means that thinking is part of discipleship. It means we do not check our brains at the door when we come to worship. We read, we study, we ask questions, we test what we hear. Jesus himself engaged in careful reasoning from Scripture, and he expects his followers to do the same. A faith that never thinks is a faith that will not last under pressure.
Loving God with the heart means that our affections matter. It is possible to hold correct beliefs while caring more about reputation, comfort, or approval than about God. The heart is where our loves are ordered. Loving God with the heart means that our deepest loyalty is being reoriented away from lesser things and toward him. This is not something we manufacture by willpower; it is the work of God's Spirit within us, but it is also something we pursue.
Loving God with strength means that our bodies and our daily energy are offered to him. It is the labor of the hands, the hours of the day, the choices about how we spend our money and time. Paul would later tell the Romans to present their bodies as a living sacrifice. That is the same idea. Wholehearted love is not a feeling that stays inside; it moves out into concrete acts of service and obedience. The scribe in Mark 12 understood this, and Jesus told him he had answered wisely.
The second commandment: love your neighbor as yourself
Jesus does not stop at the first commandment. He adds a second from Leviticus 19:18: love your neighbor as yourself. He says there is no other commandment greater than these. The two are joined. You cannot claim to love God while treating people with contempt. The vertical and horizontal dimensions of love are bound together in Jesus' answer, and he refuses to let them be separated.
The neighbor in Leviticus is not only the person next door who looks like us. The context of Leviticus 19 includes the foreigner and the poor. Jesus himself expands the definition in the parable of the Good Samaritan, where the neighbor turns out to be the one we would least expect. Loving our neighbor as ourselves means giving them the same basic care, dignity, and attention we naturally give to our own interests.
Loving neighbor is not the same as agreeing with everyone or never confronting sin. Scripture speaks of love as truthful. But the default posture of a person who loves God is a posture of mercy, patience, and generosity toward others. If our theology makes us harsh, suspicious, and eager to condemn, something has gone wrong. The second commandment holds up a mirror to our treatment of the people God has placed around us.
Notice that Jesus says the second is like the first. They are of the same kind. Love for God is not complete without love for people, and love for people is not properly grounded without love for God. When we love our neighbor only out of human goodwill, we may do good things, but we miss the God who commanded it. When we love God only in private devotion and neglect the person in front of us, we have divided what Jesus joined together.
Not far from the kingdom: Jesus' word to the scribe
In Mark 12:32-33 the scribe responds by agreeing and even summarizing the answer himself, saying that to love God with all the heart, understanding, and strength, and to love one's neighbor as oneself, is more than all whole burnt offerings and sacrifices. He has understood something profound. He has grasped that the moral heart of the law outweighs its ceremonial shell. Jesus sees that he has answered with understanding and tells him he is not far from the kingdom of God.
That phrase is both encouraging and searching. It is encouraging because the scribe is close. He has the right instincts about what matters most. It is searching because close is not the same as inside. The kingdom of God is not merely a set of correct opinions about ethics. It is the reign of God in the person of Jesus. A person can be near the kingdom and still need to enter it by trusting the King himself.
This scribe is a helpful picture of where many people stand. They admire Jesus' teaching. They agree that love is the greatest thing. They may even try to live by it. But the command to love with all the heart is impossible to keep on our own, and the gospel is not merely a higher standard; it is the announcement that God has done for us what we could not do. The one who gave the greatest commandment is the one who kept it perfectly on our behalf.
Mark tells us that after this, no one dared to ask Jesus any more questions. The debate was over. Jesus had answered the greatest question about the greatest commandment, and the answer pointed beyond itself to the King who was standing in the temple courts. To love God is to love the Son he sent, and to love the Son is to keep his commandments, as John will later write. The scribe's nearness is a call to all of us to move from admiration to trust.
If you love me, keep my commandments
Jesus makes the connection between love and obedience explicit in John 14:15, where the supplied text reads, John 14:15-24 says, "If you love me, keep my commandments." Love for God is not measured by how strongly we feel on a given day but by whether we do what he says. That does not mean obedience earns his love. It means obedience flows from love that has already been received. The order matters: we are loved, and therefore we obey.
This is where the popular idea of love as pure sentiment falls apart. In the Bible, love is a loyal commitment that shows itself in action. A husband who says he loves his wife but ignores her requests is not loving her well. A child who says he loves his parents but disobeys them is not loving them in the biblical sense. In the same way, we cannot claim to love God while living as though his commands do not apply to us.
At the same time, obedience without love is dead. Jesus criticized the Pharisees for tithing mint and cumin while neglecting the weightier matters of the law. They were meticulous in some things and loveless in others. The goal is not to become experts at rule-keeping while our hearts grow cold. The goal is a life in which love for God produces a genuine desire to do what pleases him.
John later writes in 1 John 5:1-3 that whoever believes that Jesus is the Christ has been born of God, and that this is the love of God, that we keep his commandments, and his commandments are not burdensome. That last phrase is striking. When love for God is alive, his commands are not a heavy weight but a reasonable response. They are the shape of a life that has been loved first.
We love because he first loved us
The most important truth about loving God is that it begins with God, not with us. First John 4:19 says, "Many more believed because of his word." Our love is a response, not an origin. We did not initiate the relationship; God did. He chose Israel, he sent prophets, and he sent his Son. Before we loved him, he loved us and gave himself for us. This is the fuel of wholehearted love.
That means the way to grow in love for God is not to grit our teeth and try to feel more. It is to look more closely at what he has done. The more clearly we see his love in the cross, the more naturally our love responds. Meditation on Scripture, prayer, and participation in the life of a local church all help to keep the gospel in front of us so that our affections are warmed by the truth rather than manufactured by pressure.
It also means that our failures do not end the relationship. When we realize we have not loved God with all our heart, we do not need to hide or pretend. We confess, we receive forgiveness, and we keep walking. First John 4:19-21 also warns that anyone who claims to love God while hating a brother is a liar. Love for God and love for people are tested together. The person who says he loves God but despises the people around him has not understood the love he claims to have received.
So how do you love God? You hear his word and take it seriously. You let the truth about who he is shape your whole life. You bring your mind, your affections, your body, and your daily choices under his lordship. You love the people he places around you. And you keep coming back to the cross, where you see that he loved you first, and where your own love is renewed again and again.
Biblical fidelity check
Mark 12:28-34 clearly establishes that Jesus identified love for God and love for neighbor as the greatest commandments, and that this love involves the whole person. It does not establish that feelings are irrelevant, nor does it establish that obedience is optional. It also does not teach that love for neighbor replaces love for God or that doctrine does not matter. Jesus quotes the Shema, which is a confession about who God is, and he treats the commandments as a unified whole.
A common misreading is to take the phrase love God as a purely inward, emotional experience with no necessary connection to how we live. On that reading, someone can neglect prayer, ignore Scripture, and treat others poorly while insisting they love God in their heart. But Jesus joins love to commandment-keeping, and John says plainly that anyone who does not love his brother cannot love God. The biblical picture is not feeling without action, but a whole life oriented toward God, expressed in trust, worship, and mercy toward others.
Other passages that speak to Mark 12:28-34
Several passages fill out the picture of wholehearted love and obedience. 1 John 3 Bible Study: Love in Action and Truth shows how love is tested by deeds rather than words. 1 John 4:8 Meaning: God Is Love grounds our love in God's own character. Deuteronomy Bible Study Guide: Covenant Love and Wholehearted Obedience traces the Shema back to its original setting. And 1 Corinthians 13 Meaning: What Biblical Love Is—and Is Not describes what love looks like in practice.
Frequently asked questions
Is loving God a feeling or a choice?
In Scripture, love for God includes both affection and commitment, but it is fundamentally a matter of the will before it is a matter of feeling. Jesus commands us to love God, which means it is something we can choose to pursue even when emotions are dull. Feelings often follow obedience. As we spend time in God's word, pray, and live in obedience, our affections are gradually reshaped. The Bible never treats love for God as a mood that comes and goes, but as a loyalty that endures through changing circumstances.
How can I love God when I do not feel anything?
Start with the truth rather than your feelings. First John 4:19 says, "Many more believed because of his word." Read that verse slowly. Remember that God's love for you does not depend on how warm your heart feels today. Then do the next right thing: pray honestly, open Scripture, keep your commitments, serve someone else. Feelings are unreliable, but God's word is not. Many believers find that love returns not by chasing a feeling but by returning to the ordinary means of grace.
Does loving God mean I have to keep all his commandments perfectly?
No one keeps God's commandments perfectly except Jesus himself, and the gospel is not a demand for flawless performance. It is the good news that Jesus kept the greatest commandment on our behalf and bore the penalty for our failures. Because we are forgiven, we obey out of gratitude rather than fear. Our obedience will be imperfect in this life, but it is real, and it grows. First John 5:3 says his commandments are not burdensome, because love makes obedience a willing response rather than a heavy weight.
