1 John 5:2

The English Standar Version

By this we know that we love the children of God, when we love God and obey his commandments.

See the chapter Copy

but whoever keeps his word, in him truly the love of God is perfected. By this we may be sure that we are in him:

And this commandment we have from him: whoever loves God must also love his brother.

These things I command you, so that you will love one another.

And by this we know that we have come to know him, if we keep his commandments.

We know that we have passed out of death into life, because we love the brothers. Whoever does not love abides in death.
