King James wording
King James Version
In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.THE KEY
This verse makes belonging visible: alignment with God and love for your brother are expressions of the same nature.
THE MEANING
The verse speaks to you now: what is aligned with God becomes visible in both your actions and your love for your brother. It names lovelessness as the visible mark of a nature opposed to God, the Slanderer’s nature.
WHAT THIS UNDOES
I can belong to God while refusing love to my brother; a claim of belonging is enough.

THE PATTERN
What is aligned with God becomes visible through just action and love, not through a claim alone.
You will know them by their fruits. Do people gather grapes from thorns, or figs from thistles?So also trust, if it has no works, is dead, by itself.Doing alignment and judgment is more chosen by the LORD than the slain offering.THE THREAD
If anyone says, "I love God," and hates his brother, he is a liar. For the one who does not love his brother, whom he has perceived, cannot love God, whom he has not perceived.The Greek repeats ἀγαπάω (agapaō, love) and ἀδελφός (adelphos, brother), the same words at the heart of this verse. It makes the connection concrete: love for the unseen God becomes visible in love for the brother who is seen.
