By this we know that we love the children of God, when we love God and keep His commandments.
But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him.
And this commandment we have from Him: that he who loves God must love his brother also.
These things I command you, that you love one another.
Now by this we know that we know Him, if we keep His commandments.
We know that we have passed from death to life, because we love the brethren. He who does not love his brother abides in death.
