<p>3:10 <em>In this the children of God are manifest, and the children of the Devil. Whoever does not practice righteousness is not of God, nor is he that does not love his brother</em>- The allusion is to the Lord's words in Jn. 8:44, where the children of the devil clearly refer to the Jewish leadership. The doing of righteousness is epitomized in loving our brother, which is presented as the one great commandment which is imperative in the very person of the Lord. To walk in His light is to become like Him, bit by bit. The Judaist infiltrators were controlled by the &quot;devil&quot; of the Jewish system. They did not love their Christian brethren but worked against them; and they did not love God's only begotten Son.</p>
