The Greatest Commandment (Mark 12:28–34)
What is supreme in life? The law. Because every person lives under the law. Fail to keep the law and consequences follow. There are written laws that set out various statutes and rules, and unwritten laws such as customs and traditions. There is also the law of conscience. The universe itself moves according to laws. All the authority and power behind these laws comes from God. Everything moves according to what God has established and purposed.
In Mark 12:28–34, Jesus taught a scribe the greatest of all commandments. It is to love the Lord God, the sovereign of all creation, and to love one's neighbor as oneself. This is because God first loved us who had fallen into sin to the point of sacrificing his own Son. God is always love.
Which Commandment Is the First?
28 One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, "Of all the commandments, which is the most important?" (Mark 12:28)
The scribes were scholars who studied the law and copied the Scriptures. The law governing Jewish society was the law of Moses. Even today, when the Sabbath comes, the streets of Jerusalem fall silent, with no cars passing through. This is why preserving and interpreting the law was a matter of supreme importance, and the scribes formed one of the pillars of the religious groups that dominated society.
One of the scribes had been listening to the Pharisees and Sadducees come and test and debate with Jesus. This man was moved by Jesus' words. As a scholar who studied and explored the law, he asked out of genuine curiosity which commandment was the first of all.
God's commandments include the Ten Commandments and a total of 613 laws, broadly divided into moral law, civil law, and ceremonial law. It is no easy task to determine which commandment among so many stands above the rest. In truth, not a single commandment is unimportant. This is because every commandment is a word of God's truth (Matt. 5:18).
God's commandments are like a mirror that reflects his character. God's word is the authority and power that shines light on and gives understanding of the power and glory of his invisible kingdom (Rom. 2:19). His commandments are the words of truth that reveal who he is and what people are. God's commandments govern human life. For those who do not have the law, the law of conscience written on their hearts governs them (Rom. 2:14–15). Murder, for example, is a crime and subject to condemnation everywhere in the world.
"All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law." (Rom. 2:12)
God's law — if not kept — means certain death. So then, how is the law kept? By the law of faith. Keeping the law means keeping every single provision without exception, always. The problem is that no one can keep it, so every person stands under condemnation (Gal. 3:10–12; 5:3–4; Rom. 3:20). Therefore, no one can be made righteous by the law. The way to be justified before God is faith in his Son, the Lord Jesus Christ.
Then why did God give a law that cannot be kept? That is precisely the point. It was given to teach the truth that people cannot keep God's holy law and commandments by their own strength, effort, or willpower — that is, to bring awareness of sin. This is because sin through Adam's fall caused people to become corrupt and broke the loving relationship with God. To teach this truth, God gave the law, which is like a mirror. This is how to use the law properly.
“We know that the law is good if one uses it properly (legitimately).” (1 Tim. 1:8)
"The law brings wrath, and where there is no law there is no transgression" (Rom. 4:15). One might then think: if there is no law, there is no sin. That is not so. Sin existed before the law came, but the law came so that the trespass might increase (Rom. 5:13; 7:13). Before the law came, sin was not reckoned as sin — and that itself is lawlessness and sin (1 John 3:4).
Every person, including Jews, cannot fully keep God's law (Rom. 3:10). So God sent his Son Jesus Christ, who had no sin, to take away our sins (1 John 3:5). To save us who were spiritually dead because of sin, Christ willingly gave his body completely. God sees the blood of his Son, blots out the sins of those who believe, and pours out eternal life on them (1 John 1:7; Isa. 43:25; 44:22).
Therefore, in Christ a way has now been opened to fully keep God's holy law. That way is faith in Christ Jesus who shed his blood and died on the cross. The blood of Jesus is the power and authority to forgive the faults and sins we could not keep. Believing this truth and confessing and acknowledging our helpless weakness is the beginning of entering the path of fully keeping the law — from beginning to end, depending on the grace of Christ's blood. When the first man Adam and the woman confessed that they had eaten the fruit of that tree, God clothed them with garments of skin (Gen. 3:21).
Love God and Love Your Neighbor as Yourself
29 "The most important one," answered Jesus, "is this: 'Hear, O Israel: The Lord our God, the Lord is one. 30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.' 31 The second is this: 'Love your neighbor as yourself.' There is no commandment greater than these." (Mark 12:29–31)
Jesus said first, love God with all your heart, soul, mind, and strength; and second, love your neighbor as yourself. This is the greatest commandment, and there is none greater than these. Yet God first loved this world and sent his Son as an atoning sacrifice for our sins (1 John 4:10). Therefore, in response to that love shown first to us, it is only right that we love God and love one another (1 John 4:11).
God's love is not something spoken only with the lips — it is a love that hurts. God loved us, who had fallen into sin and had no choice but to face destruction, to the point of not sparing his one and only Son but handing him over to the cross in the most brutal manner (Rom. 5:8). God's love is a love that sacrificed his one and only Son. Because there is no forgiveness of sins without the shedding of blood, God turned his Son away without mercy (Heb. 9:22; Isa. 53:10).
"Yet it was the Lord's will to crush him and cause him to suffer, and though the Lord makes his life an offering for sin, he will see his offspring and prolong his days, and the will of the Lord will prosper in his hand." (Isa. 53:10)
How do we love God? By responding to his love — believing and obeying his word. The proof of loving God is obedience to his word. To not keep and obey his commandments is to not be in God's love and to not know his love.
"This is how we know that we love the children of God: by loving God and carrying out his commands. In fact, this is love for God: to keep his commands. And his commands are not burdensome." (1 John 5:2–3)
We are also to love our neighbor as ourselves. Yet that love does not come from us — it comes from God. Love belongs to God (1 John 4:7). Whoever knows God loves their neighbor with his love. But whoever does not love does not know God (1 John 4:8).
What kind of love is God's love? God's love is giving, giving, and giving. It is a sacrificial love that did not spare his one and only Son but gave him up for sinners. God's love is a love of painful sacrifice that includes terrible death. It is not emotional love. It is a love that endures shame, mockery, and rejection. It is a holy love that includes the atoning death that blots out sin. It is an unconditional love. Not because we recognized our sin and asked for forgiveness, but he loved us while we were still sinners.
Therefore, loving our neighbor also means extending God's love — a love that includes pain and sacrifice. It is a love that involves self-denial, sacrifice, and suffering. It is a love that endures shame and insult. It is a love in which self dies and disappears. It is a love that yields and accepts loss. At the Last Supper with his disciples, Jesus gave a new commandment.
"A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another." (John 13:34–35)
Jesus' new commandment is to love one another as Christ has loved us. Jesus first did not consider equality with God something to be used to his own advantage, but took on the form of a servant and was incarnate in human likeness. And Jesus carried the sins of this world and obeyed God the Father to the point of dying on the cross, shedding his blood (Phil. 2:6–8).
Giving up one's own life — that is God's love. We love our neighbor as ourselves with this love. We cannot do this by our own strength. Nor does this love come from us. This love is God's holy love and comes from him. This love is spiritual, holy, and eternal. By this love we have become God's children, and as God's children we live by this love.
You Are Not Far from the Kingdom of God
32 "Well said, teacher," the man replied. "You are right in saying that God is one and there is no other but him. 33 To love him with all your heart, with all your understanding and with all your strength, and to love your neighbor as yourself is more important than all burnt offerings and sacrifices." 34 When Jesus saw that he had answered wisely, he said to him, "You are not far from the kingdom of God." And from then on no one dared ask him any more questions. (Mark 12:32–34)
God desires obedience more than sacrifice (1 Sam. 15:22). David, after sinning, became aware of his sin, and in repentance said that God does not desire burnt offerings of animals but looks at the center of the heart. Indeed. God looks to see whether a person repents from the very center of their heart and turns back to the Lord. God does not judge people by outward appearance but looks at the thoughts and motives of the heart.
"You do not delight in sacrifice, or I would bring it; you do not take pleasure in burnt offerings. My sacrifice, O God, is a broken spirit; a broken and contrite heart you, God, will not despise." (Ps. 51:16–17)
Loving God and loving one's neighbor as oneself is the greatest commandment. It is right that we love one another as this commandment says. That is why Jesus told the scribe who had answered wisely that he was not far from the kingdom of God. This means that since he now knew what God's greatest commandment was, what must follow is acting accordingly. To understand and know God's word yet not obey it is like a house built on sand.
"Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash." (Matt. 7:24–27)
Amen!
