1John.3.10

Here's how you tell the difference between God's children and the Devil's children: The one who won't practice righteous ways isn't from God, nor is the one who won't love brother or sister. A simple test. [JC]

1John.3.10

This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God; nor is anyone who does not love his brother.

1John.3.10

In this the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God, nor is he who does not love his brother.

1John.3.10

So now we can tell who are children of God and who are children of the Devil. Anyone who does not obey God's commands and does not love other Christians does not belong to God.
