If you know that He is absolutely righteous, you know [for certain] that everyone who practices righteousness [doing what is right and conforming to God’s will] has been born of Him.

Little children (believers, dear ones), do not let anyone lead you astray. The one who practices righteousness [the one who strives to live a consistently honorable life—in private as well as in public—and to conform to God’s precepts] is righteous, just as He is righteous.
