I like both Sab and Desirous' suggestions. You may add to Sab's the idea that Jesus waited until he was 30 and the Borg is dunking little kids.
Does your husband "take the lead" in "Family Worship Night"? Ask him if he would be willing to take the next year and dedicate "Family Worship Night" to reading and discussing the Bible ALONE without ANY literature. You can take turns choosing what scriptures/passages to read and discuss.
If you can get him to agree, then we will have plenty of suggestions for you. If he is unwilling to address God's Word free from the chains of Watchtower interpretation then you're extremely unlikely to reach him via the scriptures. But if he's willing to JUST READ the Bible and discuss what it SAYS, not what the publishing cult in New York interprets it to mean, then you have some hope.
