By this we know that we love the children of God, when we love God and keep his commandments.
“I command these things to you, that you may love one another.
This is how we know that we know him: if we keep his commandments.
But God’s love has most certainly been perfected in whoever keeps his word. This is how we know that we are in him:
We know that we have passed out of death into life, because we love the brothers. He who doesn’t love his brother remains in death.
This commandment we have from him, that he who loves God should also love his brother.
