The Great Commandment / Matthew 22:36-40
The Essence of the Law
Throughout the biblical narrative, humanity has continually wrestled with discerning what God fundamentally requires. In the Gospel accounts, religious leaders frequently sought to distill the vast corpus of Mosaic law into essential principles. When a scribe approached Jesus in the Gospel of Mark to ask which commandment was foremost of all, Christ did not offer a novel theological invention. Instead, He pointed directly back to the foundational tenets of Israel’s covenantal faith: the call to love God wholly and to love one’s neighbor as oneself.
Mark 12:28-31 (NASB)
One of the scribes came and heard them arguing, and recognizing that He had answered them well, asked Him, ‘What commandment is the foremost of all?’ Jesus answered, ’The foremost is, ‘HEAR, O ISRAEL! THE LORD OUR GOD IS ONE LORD; AND YOU SHALL 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, ‘YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.’ There is no other commandment greater than these.’
By uniting the declaration of Deuteronomy 6 with the ethical mandate of Leviticus 19, Jesus revealed that authentic devotion to God cannot be reduced to external ritual or intellectual assent. True faith demands the comprehensive allegiance of the human person, verified and made visible through active love for others.
The Anatomy of Devotion: Parsing the Shema
Christ began His response with the foundational prayer of Israel known as the Shema. For centuries, faithful Israelites recited these words daily, acknowledging the absolute oneness of God and their total allegiance to Him.
Deuteronomy 6:4-5 (NASB)
’Hear, O Israel! The LORD is our God, the LORD is one! ’You shall love the LORD your God with all your heart and with all your soul and with all your might.
The opening imperative, Shema, is far richer in biblical Hebrew than mere passive auditory reception. In the Old Testament idiom, to hear God is intrinsically bound to responding in obedience. Biblical Hebrew possesses no distinct word for “obey”; rather, true hearing assumes action. When God calls His people to hear His voice, genuine hearing is demonstrated only through covenant fidelity.
Exodus 19:5 (NASB)
’Now then, if you will indeed obey My voice and keep My covenant, then you shall be My own possession among all the peoples, for all the earth is Mine;
The response demanded by the Shema is ahavah—love. Far from being a fleeting emotional state, biblical love is active, covenantal, and sacrificial. It reflects the very character of God, who demonstrates His love not through mere sentiment, but through redemptive action on behalf of the vulnerable and oppressed.
Deuteronomy 10:18-19 (NASB)
’He executes justice for the orphan and the widow, and shows His love for the alien by giving him food and clothing. ’So show your love for the alien, for you were aliens in the land of Egypt.
This love for God is to engage the totality of the human faculties: the levav (heart), the nephesh (soul), and the me’od (strength). In ancient Hebrew thought, the heart was not merely the seat of emotions, but the primary center of intellect, discernment, and volitional decision-making. The nephesh refers to the throat, breath, and the living physical being itself—the entire embodied person. Finally, me’od is an intensifier denoting “muchness” or utmost capacity. To love God with all one’s me’od is to direct all available resources, power, and capacity toward honoring Him. Loving God requires an integrated, whole-person consecration.
The Inseparable Mandate: Loving the Neighbor
Jesus immediately coupled the Shema with a second commandment from the Holiness Code of Leviticus: “You shall love your neighbor as yourself.” In the divine economy, these two commandments are inseparable. Love for the invisible God is made tangible through love for His image-bearers.
Leviticus 19:18 (NASB)
’You shall not take vengeance, nor bear any grudge against the sons of your people, but you shall love your neighbor as yourself; I am the LORD.
Scripture explicitly widens the definition of “neighbor” beyond ethnic, social, or geographic boundaries. In the same chapter of Leviticus, God commanded Israel to extend this identical standard of love to the alien and the stranger residing among them.
Leviticus 19:34 (NASB)
’The stranger who resides with you shall be to you as the native among you, and you shall love him as yourself, for you were aliens in the land of Egypt; I am the LORD your God.
Christ reinforced this universal obligation in the Parable of the Good Samaritan, demonstrating that neighboring is not defined by proximity or affinity, but by the willingness to show active mercy to those in distress. True love crosses social barriers to bear the burdens of the broken, the destitute, and the marginalized.
Luke 10:36-37 (NASB)
‘Which of these three do you think proved to be a neighbor to the man who fell into the robbers’ [hands]?’ And he said, ‘The one who showed mercy toward him.’ Then Jesus said to him, ‘Go and do the same.’
The Integrity of Inward Reality and Outward Practice
A central danger in religious practice is the divergence between external presentation and inward reality. Religious activity, theological precision, and ritual observances can easily project an appearance of spiritual maturity while the interior life remains cold and untouched by divine grace. The scribe who questioned Jesus recognized this profound truth, affirming that wholehearted love for God and neighbor surpasses all burnt offerings and formal sacrifices.
Mark 12:32-34 (NASB)
The scribe said to Him, ‘Right, Teacher; You have truly stated that HE IS ONE, AND THERE IS NO ONE ELSE BESIDES HIM; AND TO LOVE HIM WITH ALL THE HEART AND WITH ALL THE UNDERSTANDING AND WITH ALL THE STRENGTH, AND TO LOVE ONE’S NEIGHBOR AS HIMSELF, is much more than all burnt offerings and sacrifices.’ When Jesus saw that he had answered intelligently, He said to him, ‘You are not far from the kingdom of God.’ After that, no one would venture to ask Him any more questions.
Because God is entirely self-sufficient, He requires nothing from human hands. Consequently, devotion to God cannot be paid directly to Him through religious barter; instead, He directs human love outward toward His creation. Loving humanity is the practical theater in which love for God is authenticated. Where love for the neighbor is absent, claims of loving God are rendered hollow.
Conclusion
The Great Commandment establishes the ultimate metric of Christian discipleship. God does not seek superficial compliance or fragmented devotion, but the complete engagement of the human heart, soul, mind, and strength. When the soul is truly captivated by the love of God, that affection inevitably overflows into costly, tangible service to others. In uniting love of God with love of neighbor, Christ provides both the standard of kingdom righteousness and the enduring definition of a life fully aligned with the heart of God.
