Here are some questions I might ask my Sabbath School class to get discussion started:

1. What specifics did Christ mention about the earliest marriage mentioned in Genesis?

2. What changed when sin entered the picture?

3. What did Christ do to change the mess sin had made of marriage?

Note: sin had caused marriage to dip to a low point in Christ's day. If you study Roman marriage during the days of the emperors, you will see what I mean.
