Honing in on holiness - How an unbelieving husband is sanctified through his wife (1Cor 7:14)

Who you hang with will sharpen or dullen you.

For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband. Otherwise your children would be unclean, but as it is, they are holy. (1Cor 7:14 NIV)

So how does this work? How is it that an unbelieving man can be sanctified through a Christian woman? The bi-product of sanctification is to sin less. It is to become increasingly Christ-like in one’s deeds and actions. It is holy living. So now presume we have a very carnal man, which loves over-drinking, is a brawler, and loves to steal things. These are sinful activities. Yet, by living with this Godly woman, the very nature of her presence will have a positive influence on him. Her light will bother his darkness. He might even occasionally go to Church. And he will moderate his wicked conduct to appease her sensitivities. If he is going to over-drink, but remembers it upsets her (and that she will cry) he will be more inclined to avoid inebriation (or have the shame to at least hide it). If he is tempestuous and wants to punch some bloke’s nose, she might encourage him to walk away and be the better man. Her influence will calm his evil inclinations. Her love will calm his hate. If he is going to steal something from a store, he will be discouraged by remembering that his wife will think less of him if he did. Her influence has a braking effect on his evil tendencies and inevitably draws him into a holier lifestyle (against his nature). The believer sanctifies the unbeliever. This is not to say that the unbeliever’s heart moves closer to God, but that their conduct is swayed by the believer’s influence. (Side note: please remember, we are not to marry unbelievers. This verse in question speaks of a conversion within an existing marriage).
