1 Corinthians 7:14-15

7:14 For the unbelieving husband is sanctified because of the wife, and the unbelieving wife because of her husband. Otherwise your children are unclean, but now they are holy. 7:15 But if the unbeliever wants a divorce, let it take place. In these circumstances the brother or sister is not bound. God has called you in peace.

1 Corinthians 14:5

14:5 I wish you all spoke in tongues, but even more that you would prophesy. The one who prophesies is greater than the one who speaks in tongues, unless he interprets so that the church may be strengthened.
