2 Corinthians 6:11-14

O ye Corinthians, our mouth is open unto you, our heart is enlarged. Ye are not straitened in us, but ye are straitened in your own bowels. Now for a recompence in the same, (I speak as unto my children,) be ye also enlarged. Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
