In this way, we are certain that we have love for the children of God, when we have love for God and keep his laws.
So this is my law for you: Have love one for another.
And by this we may be certain that we have knowledge of him, if we keep his laws.
But in every man who keeps his word, the love of God is made complete. By this we may be certain that we are in him:
We are conscious that we have come out of death into life because of our love for the brothers. He who has no love is still in death.
And this is the word which we have from him, that he who has love for God is to have the same love for his brother.
