Is There a Proximity Issue With Holiness?

If you have somebody in a household who is a believer, they are then closer to christ than they would otherwise be. God means for christian parents to raise their children in the faith as gifts from his hand. And so by virtue of being given to you as a believer holy, then you are baptizing them, and they too then are made holy. So they are, they are made holy by virtue of the same way that you are made holy, regardless of whether the the spouse is believing or not.
