If you know that he is righteous, you know that everyone who practices righteousness is born of him.

 John is pleading with his people to abide in the things which they have learned, for, if they do, they will abide in Christ. The great interest of this passage lies in an expression which John has already used. In 1 John 2:20 he has already spoken of the anointing which his people had had from the Holy One and through which all of them were equipped with knowledge. Here he speaks of the anointing which they have received and the anointing which teaches them all things. What is the thought behind this word anointing? We shall have to go back some distance in Hebrew thought to get at it.
