Which is the greatest commandment according to Jesus? The Core of His Teachings Explained

In the bustling heart of ancient Jerusalem, amidst the throngs of people seeking wisdom and guidance, Jesus was once asked a question that has echoed through the ages: "Which is the greatest commandment in the Law?" This wasn't a casual inquiry; it was a deliberate test posed by a scholar of the Law, hoping to trap Jesus. Yet, his answer, recorded in the Gospels, not only disarmed the questioner but revealed the absolute bedrock of his teachings. So, what did Jesus deem the greatest commandment?

Jesus Identifies Two Core Commandments

Jesus, with his characteristic insight, didn't just pick one from the complex tapestry of Jewish law. Instead, he pointed to two, declaring them inseparable and foundational. He stated:

"The most important one," answered Jesus, "is this: 'Listen, Israel, the Lord our God is the only Lord. Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.' The second is this: 'Love your neighbor as yourself.' There is no commandment greater than these."

This answer, found in passages like Mark 12:28-31, Matthew 22:36-40, and Luke 10:25-28, is profoundly significant. Jesus essentially condensed the entirety of God's law, all the Ten Commandments and the thousands of other statutes and ordinances, into these two overarching principles.

The First Great Commandment: Love God Above All Else

The first commandment Jesus highlights is a direct quotation from the Old Testament, specifically Deuteronomy 6:4-5, known as the Shema. It's a declaration of monotheism and a call to complete devotion:

With all your heart: This speaks to our deepest emotions, our affections, and our passions. Loving God with all your heart means allowing Him to be the primary focus of your emotional life.
With all your soul: This refers to our entire being, our very existence. It's about dedicating our innermost selves to God.
With all your mind: This involves our intellect, our thoughts, and our understanding. It's about actively engaging our minds in knowing and obeying God, thinking His thoughts after Him.
With all your strength: This encompasses our physical capabilities and our willpower. It means using all the energy and resources God has given us in service to Him.

This isn't a passive love; it's an active, all-consuming devotion that permeates every aspect of a person's life. It's about recognizing God's unique sovereignty and His inherent worthiness of our ultimate allegiance.

The Second Great Commandment: Love Your Neighbor

The second commandment Jesus cites is from Leviticus 19:18. He presents it as directly connected to the first, calling it "like it."

Love your neighbor as yourself: This command is the practical outworking of the first. If we truly love God, that love will naturally extend to the people He created. It means treating others with the same care, respect, and consideration that we naturally have for ourselves.

Jesus' emphasis here is crucial. He broadened the definition of "neighbor" in other teachings, famously illustrated in the Parable of the Good Samaritan (Luke 10:29-37), showing that our neighbor is anyone in need, regardless of their background or our relationship with them.

Why These Two? The Interconnectedness

Jesus' brilliance lies in his ability to distill complex truths into simple, yet profound, principles. He saw these two commandments as inextricably linked:

Love for God breeds love for humanity: A genuine, heartfelt love for God, who is the Creator and sustainer of all, naturally leads to a love for His creation, which includes all people. If we claim to love God but hate our fellow human beings, our love for God is likely superficial.
Love for humanity reflects love for God: Conversely, demonstrating love and compassion towards others is a tangible way of loving and obeying God. As John famously wrote in his first epistle, "If anyone says, 'I love God,' but hates a brother or sister, that person is a liar; for if they do not love a brother or sister whom they have seen, how can they love God whom they have not seen?" (1 John 4:20).

Jesus' answer was revolutionary because it shifted the focus from external adherence to internal motivation. It wasn't just about following rules; it was about cultivating a heart that reflects God's own character of love.

The Implications for Today

For Christians and those seeking to understand Jesus' teachings, these two commandments remain the ultimate guide. They provide a framework for:

Our relationship with God: A sincere pursuit of knowing and loving God more deeply.
Our relationships with others: A call to empathy, kindness, and justice in all our interactions.
Navigating ethical dilemmas: Asking whether our actions are motivated by love for God and love for our neighbor.

In a world often characterized by division and self-interest, Jesus' declaration of the greatest commandment offers a timeless and powerful vision for how to live a life of purpose and meaning.

Frequently Asked Questions

How did Jesus know these were the greatest commandments?

Jesus, as the Son of God and the divine revealer of God's will, possessed a perfect understanding of God's heart and purpose. He was deeply familiar with the Jewish Scriptures, which he considered authoritative. By identifying these two commandments, he was drawing from the foundational texts of the Old Testament (Deuteronomy and Leviticus) and presenting them as the essence of all divine instruction. His divine nature allowed him to discern and articulate the core intent behind the Law.

Why did Jesus combine two commandments into one "greatest"?

Jesus combined these two commandments to illustrate their inseparable nature. He understood that true love for God inevitably leads to a love for God's creation, including humanity. Conversely, genuine love for our neighbor is a direct expression and evidence of our love for God. He wasn't creating a new rule but revealing the deep, interconnected reality of God's design for human relationships and devotion.

Does "neighbor" in the second commandment include enemies?

Yes, Jesus expanded the understanding of "neighbor" beyond just those we know and like. In the Parable of the Good Samaritan, he showed that a "neighbor" is anyone in need. This certainly includes those who might be considered outsiders or even adversaries. The commandment to love our neighbor as ourselves calls for compassion and care for all people, demonstrating God's love to everyone.
