The World and the Heart

 
“Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?” (2 Cor. 6:1414Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? (2 Corinthians 6:14)).
If a Christian gets into the world, the heart gets narrowed and then into deeper sin. The world is a great system, which the devil has built up around man, to give men their sphere of enjoyment.
J. N. Darby (from Gems From My Reading)
