The commandment to love is both old and new–old in its origin in the Torah, and new in the way Jesus embodies, deepens, and empowers it.
This post explains how Jesus’ “new commandment” fulfills and transforms the ancient command to love, revealing a deeper, Spirit‑empowered way of abiding in God.
Why Jesus Calls the Commandment to Love “New”
In John 13:34–35 (ESV), Jesus says:
“A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.”
But this raises a question: How can Jesus call this a new commandment when the commandment to love already appears in Leviticus 19:18 (ESV)?
“You shall not take vengeance or bear a grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.”
And to complicate things further, John writes in 1 John 2:7 (ESV):
“Beloved, I am writing you no new commandment, but an old commandment that you had from the beginning. The old commandment is the word that you have heard.”
So, is the commandment to love an old one or a new one?
How the Old Testament Command Differs
The command to love one’s neighbor was foundational to the Torah. It was part of Israel’s ethical and communal identity. That’s why John can say in his letter that this command isn’t new. It’s something believers have heard from the beginning.
In fact, 1 John 3:11 (ESV) echoes this:
“For this is the message that you have heard from the beginning, that we should love one another.”
So the idea of love isn’t new. It’s ancient. Embedded in God’s character and His covenant with His people.
What Makes Christian Love Unique?
The newness isn’t in the concept. It’s in the quality, standard, and embodiment of love.
What’s New:
- The Standard: Love modeled on Christ’s sacrificial, self-emptying love.
- The Model: Jesus Himself becomes the living example of love.
- Community Identity: Love becomes the defining mark of discipleship.
- Power: The Spirit empowers believers to love as Christ did.
Jesus says:
“Just as I have loved you, you also are to love one another.”
This is the shift. Leviticus says to love your neighbor as yourself. Jesus says to love as He has loved us. He’s set a higher bar. Not self-love, but self-sacrificial love.
How Love, Faith, and Abiding Interconnect
John 14:23 (ESV) connects love with obedience and abiding:
“If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him.”
And 1 John 2:24–25 (ESV) adds:
“Let what you heard from the beginning abide in you… And this is the promise that he made to us—eternal life.”
You may have heard the phrase that love isn’t just a feeling, it’s a choice. But it’s more than a choice. It’s action—a way of abiding in God. To love others is to dwell in God’s presence. Abiding is love, or love is abiding. If we love others, WE ARE loving God. The two are inseparable.
Faith and Love: The Work of God
John 6:29 (ESV) reminds us:
“This is the work of God, that you believe in him whom he has sent.”
And 1 John 3:23-24 (ESV) ties belief and love together with abiding:
“And this is his commandment, that we believe in the name of his Son Jesus Christ and love one another, just as he has commanded us. Whoever keeps his commandments abides in God, and God in him. And by this we know that he abides in us, by the Spirit whom he has given us.”
Faith and love are not separate tasks. They’re intertwined. Faith is our work. Love is our witness. Both prove that we are abiding in Christ.
Conclusion: Old Commandment, New Life
Jesus didn’t replace the old commandment. He fulfilled it, deepened it, and redefined it around Himself. The command to love is old in origin but new in depth, power, embodiment, and community impact.
It’s not just about avoiding grudges or vengeance. It’s about laying down our lives. Abiding in God. In this way, we will be known as Christ’s disciples.
So, yes. The commandment to love is an old one. And, in Jesus, it is new. More than that, though, because of Him the commandment becomes eternal.
