Ruth 4

So Boaz took Ruth and she became his wife; and when he went in to her, the Lord gave her conception, and she bore a son...Also the neighbor women gave him a name, saying, “There is a son born to Naomi.” And they called his name Obed. He is the father of Jesse, the father of David. vv.13, 17

Read chapter 4
So Boaz marries Ruth and they have a son and this son is Obed who is David's grandfather.  So pretty cool that this lineage goes to David which then goes to Jesus Christ, but let's look back a generation too to where it came from.  Boaz' father was Salmon but do you know who his mother was?  Rehab!  Matthew 1:5, "Salmon begot Boaz by Rahab, Boaz begot Obed by Ruth, Obed begot Jesse." Now if you don't know the story on Rahab I suggest you read Joshua 2 & 6.  In short she was a prostitute in Jericho who helped hide the Israelite spies before they conquered the city and her and her family was saved by the destruction because of her faith in the God of Israel.
So Boaz' mom was a gentile and he married a gentile.  Both foreign women who loved the God of Israel and showed their faith in powerful ways contrary to the culture around them.  Both in the lineage of Christ.
How have you seen radical change in someone that wasn't a follower of Christ or grown up in the Christian culture, come to not only know and love the Lord but also to raise a family to be followers as well?  Sad that there is a gap often in what the parents believe and what their children believe today in age.  Why do you think that is?
