In this we know that we love the children of God: when we love God, and keep his commandments.
But he that keepeth his word, in him in very deed the charity of God is perfected; and by this we know that we are in him.
And this commandment we have from God, that he, who loveth God, love also his brother.
These things I command you, that you love one another.
And by this we know that we have known him, if we keep his commandments.
We know that we have passed from death to life, because we love the brethren. He that loveth not, abideth in death.
