1 John 5:2

Catholic Public Domain Version

In this way, we know that we love those born of God: when we love God and do his commandments.

See the chapter Copy

This I command you: that you love one another.

And we can be sure that we have known him by this: if we observe his commandments.

But whoever keeps his word, truly in him the charity of God is perfected. And by this we know that we are in him.

We know that we have passed from death to life. For we love as brothers. Whoever does not love, abides in death.

And this is the commandment that we have from God, that he who loves God must also love his brother.
