“Do not be mismatched with unbelievers; for what do righteousness and lawlessness share together, or what does light have in common with darkness? Or what harmony does Christ have with Belial, or what does a believer share with an unbeliever….. ? Therefore, come out from their midst and be separate,” says the Lord. “And do not touch what is unclean; And I will welcome you.”                    2 Corinthians 6:14-15, 17  NASB2020. https://bible.com/bible/2692/2co.6.17.NASB2020

The chief duty of Christian parents is to raise godly children. Godly children are the product of knowing God and His ways then embracing them for themselves. One area that derails Christian children, especially young woman, is their choice of boyfriend and spouse. These young women embrace a relationship with a young man who is not a Christian. Christian fathers say nothing to their Christian daughters about this relationship. Some young men do come to faith. More often, young woman lose their faith or place it in dormancy. If they marry these unbelievers then what? Grandchildren are created who will not learn of God from their parents and so embracing the ways of God becoming infinitely more difficult. Christian fathers in particular have the duty to teach their children to be a godly spouse and to choose for themselves godly spouses. There is no alternative to this Christian teaching. The will of God is for the people of God to grow and increase. They are to grow in their faith through their unity and they are to grow the faith through their unity. The kingdom of God is to continue generationally through godly parents raising godly children who produce more godly children. Israel was destroyed due in part to the corruption of their nation caused by mixed marriages, so too many children who grew up in Christian homes have shipwrecked their faith marrying others who do not love the Lord. This should not be and Christian fathers must work hard by teaching diligently God’s truth to their children and insisting upon following God’s ways as long as the children are living in his home.
