One of the clearest passages concerning fellowship is found in 2 Cor. 6:14-18: "Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness...wherefore come out from among them, and be ye separate, saith the Lord...and I will receive you, and will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty".
Kwa hiyo tokeni kati yao, mkatengwe nao, asema Bwana,….. nami nitawakaribisha, nitakuwa Baba kwenu, nanyi mtakuwa kwangu wanangu wa kiume na wa kike, asema Bwana mwenyezi".
