1 Wakorintho 7 : 14 1st Corinthians chapter 7 verse 14

Kwa maana yule mume asiyeamini hutakaswa katika mkewe; na yule mke asiyeamini hutakaswa katika mumewe; kama isingekuwa hivyo, watoto wenu wangekuwa si safi; bali sasa ni watakatifu.
soma Mlango wa 7

For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the husband. Otherwise your children would be unclean, but now are they holy.
