Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? 2 Corinthians 6:14
Paul told the Corinthians to not be yoked together with unbelievers. He spoke of righteousness and wickedness - light and darkness, the characteristics of believers and unbelievers, respectively.
Yet, I find that wickedness and darkness are not exclusive to those outside the church. Many within our walls court the enemy. So much is done to discredit the Body of Christ by those who claim to follow Him.
What have we done to Your Body, Lord? Why do we entertain fellowship with darkness? Shine Your light of righteousness into the Church. Shine it into my life. Make me a righteous and radiant man.
