What Proceedeth?

1 John 4:20-21 — If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen? And this commandment have we from him, That he who loveth God love his brother also.

John Calvin commenting on these verses said that true love for God cannot exists unless it generates brotherly love.

In 1 John, the author is instructing the readers that love (righteousness) proceedeth from the Beloved (the righteous). However, wickedness proceedeth from the wicked (1 Samuel 24:13a). Love and desire will always manifest itself in concrete realities, generating either love/righteousness or wickedness. Our works/the concrete realities generated by our desires, therefore, are testaments of whether we love the works of Satan or love the works of a righteous God.
