What is the greatest commandment in the Bible?
Jesus answered this question directly. When He was asked which commandment was the greatest, He pointed first to loving God completely and then immediately connected it with loving our neighbor.
These two commandments provide a powerful summary of how God's people are called to live.
Jesus Was Asked About the Greatest Commandment
Matthew 22 records a lawyer asking Jesus:
"Master, which is the great commandment in the law?"
Jesus answered:
"Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind."
Then Jesus said:
"This is the first and great commandment."
According to Jesus, our highest responsibility is to love God.
Love the Lord Your God
Jesus was quoting from Deuteronomy 6:5, where Israel was commanded:
"And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might."
Loving God is more than having religious feelings.
It involves giving God our deepest loyalty, worship, trust, and obedience.
God is not meant to occupy one small part of our lives while everything else remains separate from Him. Jesus describes a love that involves the whole person.
Love God With All Your Heart
To love God with all your heart means that your inner life is directed toward Him.
Our desires, priorities, motives, and affections should increasingly reflect our love for God.
This does not mean Christians will never struggle with competing desires. It means God should hold the highest place in our lives.
Love God With All Your Soul
Our love for God should involve our whole life.
Faith is not merely something practiced for a few hours each week.
Our relationship with God should influence how we live, work, speak, make decisions, treat people, use our resources, and respond to difficulties.
Love God With All Your Mind
Jesus also says to love God with all our mind.
Christian faith does not require us to stop thinking.
We should seek to understand God's Word, grow in wisdom, recognize truth, reject falsehood, and allow our thinking to be shaped by what God has revealed.
Studying Scripture can therefore be an expression of loving God.
The Second Greatest Commandment
Jesus did not stop with the first commandment.
He continued:
"And the second is like unto it, Thou shalt love thy neighbour as thyself."
This command comes from Leviticus 19:18.
Love for God and love for other people cannot be separated in Christian living.
Who Is My Neighbor?
Someone once asked Jesus this very question.
In response, Jesus told the parable commonly known as the Good Samaritan.
A man had been attacked by robbers and left wounded beside the road. A priest passed by. A Levite also passed by.
But a Samaritan stopped.
He cared for the injured man, transported him to a place of safety, and paid for his care.
The Samaritan showed what neighborly love looks like in practice.
Our neighbor is not limited to someone who looks like us, comes from our community, or shares our background.
Love Is More Than Words
Biblical love is not merely saying, "I love you."
First John 3:18 says:
"Let us not love in word, neither in tongue; but in deed and in truth."
Love becomes visible through our actions.
It can mean helping someone in need, forgiving someone who has wronged us, speaking truth, showing patience, caring for the vulnerable, giving generously, or simply being present with someone who is suffering.
Jesus Even Commands Us to Love Our Enemies
Jesus takes the command to love even further.
In Matthew 5:44, He says:
"Love your enemies, bless them that curse you, do good to them that hate you."
This is one of the most challenging teachings of Jesus.
Christian love is not restricted to people who treat us well.
Loving an enemy does not mean calling evil good or refusing appropriate justice and boundaries. It means refusing hatred and revenge while seeking to respond in a way consistent with the character of Christ.
Love and Obedience Belong Together
Jesus did not define love for God as emotion alone.
He said in John 14:15:
"If ye love me, keep my commandments."
Obedience does not purchase God's love or salvation. Rather, obedience is one way genuine love for Christ becomes visible in a believer's life.
All the Law and the Prophets
After giving the two greatest commandments, Jesus made an extraordinary statement:
"On these two commandments hang all the law and the prophets."
Jesus was not saying that every other biblical command had become meaningless.
He was showing the underlying direction of God's commandments.
Our responsibility toward God is summarized by wholehearted love for Him, while our responsibility toward other people is summarized by love for our neighbor.
Can We Love God While Hating Other People?
First John gives a serious warning about claiming to love God while hating others.
It says:
"He that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?"
Our treatment of people matters to God.
Worship, prayer, Bible study, and Christian service should produce lives increasingly characterized by love.
Jesus Is the Greatest Example of Love
Jesus did more than command people to love.
He demonstrated love.
He showed compassion to the sick, welcomed people rejected by society, served His disciples, forgave sinners, and ultimately gave His life on the cross.
John 15:13 says:
"Greater love hath no man than this, that a man lay down his life for his friends."
The cross shows us that biblical love can be costly and sacrificial.
Love Does Not Mean Approving Everything
Christian love should not be confused with agreeing with everything another person believes or does.
The Bible connects love with truth.
We can disagree with someone while still treating that person with dignity, patience, kindness, and respect.
Love seeks another person's good rather than simply telling people whatever they want to hear.
What Does the Greatest Commandment Mean for Us Today?
The teaching of Jesus gives Christians a simple but demanding question for everyday life:
Am I loving God, and am I loving people?
We can ask this question about our families, workplaces, churches, friendships, online conversations, finances, decisions, and treatment of strangers.
Love for God should shape how we live.
Love for our neighbor should shape how we treat people.
Conclusion
What is the greatest commandment?
Jesus gave a clear answer:
"Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind."
And the second is closely connected to it:
"Thou shalt love thy neighbour as thyself."
The Christian life cannot be reduced merely to religious activity.
Jesus calls us to wholehearted love for God and genuine love for people.
We love because God first loved us, and the clearest demonstration of that love is found in Jesus Christ.
Love God. Love your neighbor. These are at the heart of faithful Christian living.
