I recently received this note from a sister in Christ. It brought me great comfort in my barrenness:

In our household we have come to love the story of Ruth. [My husband] teaches it on a cycle to the youth of our church. One of his main points is that it is as much Naomi’s story as Ruth’s and Boaz’, for it is the story of the Promise of the Seed and Naomi’s Redeemer. 

In the last chapter, when Boaz’ and Ruth’s son is born, the village women remark that Ruth was as good as ten sons to Naomi. This is true, isn’t it? Through this child comes the continuation of what will be the Davidic line resulting in David’s King. How wondrous! And yet Ruth is not Naomi’s daughter and blood relation. Instead, upon having seen and tasted her mother-in-law’s faith in her home country, Ruth is a daughter by confession. “Your people will be my people; your God, my God.”

Not all mothers give birth to their daughters.
