1 John 3:23 – “And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us.”
Extended Explanation
In this verse, John sums up the heart of the Christian life in two simple but powerful commands:
Believe in Jesus and love one another.
Everything John has been saying throughout this chapter—and really, throughout the whole letter—comes down to these two things.
First, John says that God’s command is to believe in the name of His Son, Jesus Christ.
This is not just believing facts about Jesus; it’s about trusting in Him, resting in who He is and what He has done.
Second, John says we are commanded to love one another.
This love is not optional.
It’s the natural result of truly knowing and trusting Jesus.
John is reminding us that faith and love belong together.
You can’t separate them.
If you believe in Jesus, you will love others.
Historical Context
In the early church, there was confusion and false teaching about what it meant to follow God.
Some people claimed to have special knowledge or spiritual experiences but showed no love toward others.
John is writing to make it clear:
The true test of faith is belief in Jesus and love for others.
This was a radical message in a world full of religious rules, division, and spiritual pride.
John is pointing his readers back to the simple, clear command they had heard from the beginning.
Theological Implications
This verse teaches that faith in Jesus and love for others are the two pillars of the Christian life.
You can’t claim to know God if you don’t trust in Jesus.
And you can’t claim to follow Jesus if you don’t love others.
It also shows that God’s commands are not burdensome or complicated.
They are clear: Believe and love.
Everything else flows from these two things.
Literary Analysis
John’s language in this verse is clear and straightforward.
He uses the word “command” to show that this is not a suggestion or extra teaching—it’s the foundation.
He divides the command into two parts:
- Believe in Jesus.
- Love one another.
This simple structure reflects John’s style throughout the letter: clear, practical, and focused on the essentials.

It is about two things:
Trusting in Jesus and loving people.
