1 Corinthians 7
15 Ref But if the one who is not a Christian has a desire to go away, let it be so: the brother or the sister in such a position is not forced to do one thing or the other: but it is God's pleasure that we may be at peace with one another.
16 Ref For how may you be certain, O wife, that you will not be the cause of salvation to your husband? or you, O husband, that you may not do the same for your wife?
17 Ref Only, as the Lord has given to a man, and as is the purpose of God for him, so let him go on living. And these are my orders for all the churches.
