What is what does it mean that the husband is sanctified by the wife?

The statement that the husband is sanctified by the wife refers to a biblical concept found in 1 Corinthians 7:14. In this passage, the apostle Paul explains that in a marriage where one spouse is a believer and the other is not, the unbelieving spouse is made holy by the believing spouse.

This concept of sanctification through marriage means that the presence and influence of a believer in the marriage can bring spiritual benefits to the unbelieving spouse. This does not mean that the unbelieving spouse is automatically saved, but rather that they may be positively impacted by the faith and actions of their believing partner.

In essence, when one spouse in a marriage is living out their faith in a genuine and consistent way, it can have a sanctifying effect on the other spouse, leading them closer to God and potentially influencing them to also come to faith in Christ.
