1 John 3v7-8

Heavenly Father
Give us grace today to be careful who we take advice from, taking account of the fruits of their lives

⁷ Little children, let no one lead you astray. He who does righteousness is righteous, even as he is righteous. 
⁸ He who sins is of the devil, for the devil has been sinning from the beginning. 
To this end the Son of God was revealed: that he might destroy the works of the devil.
