How does one agapao one's wife to "sanctify and cleanse her with the washing of water by the word"?

• Show her the love of 1Cor.13:4-7.
• "The family prays together, reads the Bible together, attends church together, etc. Their lives are centered round Christian principles and living." - as Lesley says in her comment. And this is in spite of being tired or having things you would rather do. After all, Jesus could have been somewhere more pleasant on Good Friday.
• The spiritual leader of the family needs to attend the church that is best for the family, not the church that is best for him in particular.
• Do what is needed, such as baby sitting, so that she can get the Bible study that she needs.

None of this requires the husband to exegete the Bible to his wife, just to do, sacrificially, what he is capable of doing.

• The spiritual leader of the family needs to attend the church that is best for the family, not the church that is best for him in particular. I have seen a problem when this wasn't done, and I have seen success when this was done.
• Do what is needed, such as baby sitting, so that she can get the Bible study that she needs.

Each of these leads to the wife being sanctified and cleansed "with the washing of water by the word".

None of this requires the husband to exegete the Bible to his wife, just to do, sacrificially, what he is capable of doing.
