1 John 3:23 says that God’s commandment is twofold: believe in the name of his Son, Jesus Christ, and love one another as he commanded. In short, trust in Jesus and love among believers are the central marks of obedience. The apostle John wrote this to the early Christian communities in the region of Asia Minor, believers who needed to know how to tell genuine faith from empty claims.
This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded.

What 1 John 3:23 Means
The word “commandment” is singular, which tells you John is treating belief and love as one command with two sides rather than two separate tasks. To believe “in the name” of Jesus Christ means more than agreeing that he existed. In biblical usage, a name stands for the person’s character and authority, so trusting in his name means relying on who he is and what he has done.
The second half asks believers to love one another “even as he commanded.” That phrase points back to Jesus’s own teaching that his followers should love as he loved them. The verse does not promise that faith will remove every difficulty or that love will always feel easy. It describes what God asks of those who belong to him and trusts that he will give what is needed to live this way.
The Context of 1 John 3:23
First John is a letter, not a gospel, and it was written to people who were already part of a Christian community. Its author is traditionally identified as the apostle John, though the letter itself does not name him. The letter repeatedly tests claims to faith by asking whether a person’s life shows God’s love and truth, and that concern runs through the whole book.
The verses just before this one, in 1 John 3:20-22, speak about a heart that condemns us and about the boldness we have before God when our hearts are at peace. Verse 23 answers the question of what a confident, obedient heart looks like in practice. Verse 24 then says that those who keep God’s commandments remain in him, which explains why John puts so much weight on this command. Read in that setting, the verse is less a rule to memorize and more a description of how fellowship with God shows itself.

John 13:34-35
34 A new commandment I give to you, that you love one another. Just as I have loved you, you also love one another. 35 By this everyone will know that you are my disciples, if you have love for one another.”

Jesus gives his disciples a new commandment to love one another as he has loved them, and he says this love will mark them as his followers. It is the same instruction John repeats in his letter, which helps show that the command comes straight from the teaching of Jesus.
John 14:1
“Don’t let your heart be troubled. Believe in God. Believe also in me.
(WEB)
Jesus tells his disciples not to let their hearts be troubled and to trust in God and in him. This connects closely to the call to believe in the name of Jesus, since it shows that trust in him is meant to steady the heart in hard moments.
A Short Prayer From 1 John 3:23
Father, you have made it clear that trusting your Son and loving one another belong together. I confess that I often believe in you on Sunday and then struggle to love the people closest to me during the week. Help me rest in who Jesus is, so that my faith is not only words but the foundation of how I treat others. Give me patience with those who frustrate me and the humility to ask forgiveness when I fall short. Let your love flow through me to my brothers and sisters, and let it be seen in ordinary days. Amen.
