1 John 2:29

(27) If ye know that he is righteous, ye know that every one that doeth righteousness is born of him.

(27) A passing over to the treatise following, which tends to the same purpose, but yet is more ample, and handles the same matter in another way, for before he taught us to go from the effects to the cause, and in this that follows, he goes from the causes to the effects. This is the sum of the argument, God is the fountain of all righteousness, and therefore they that give themselves to righteousness, are known to be born of him, because they resemble God the Father.
