In my last post I said I read Ruth 4, but I don't think I did.
In Ruth 4:1-6 we see Boaz meet the unnamed redeemer in public. He asks him to sit and also brings in 10 elders of the city to be witnesses of the conversation. I don't fully understand the conversation here, but I get the idea that Boaz knows the situation well and likely the individual. He knows that he will want to claim them, perhaps to increase his own wealth or prominence, but not out of concern for Ruth & Naomi. After all, if he had been concerned, wouldn't he have stepped up before now.
His self focused motives are further indicated by how once the full extent of what he will be required to do is revealed and how it will impact his own inheritance, he backs away.
Boaz shows himself shrewd here. He knows the person he's dealing with and he knows the situation well and he works it with the goal of protecting and providing for Ruth and Naomi.
Look then at the results. In Ruth 4:14 Naomi, who was self described up front as bitter, is now praised and called blessed by the women of the town. And Ruth becomes the Great grandmother of David, the most famous King of Israel and ultimately the ancestor of Jesus.
What did Ruth do to accomplish this? She stepped out in faith and remained true to Naomi. She stepped out in faith again when approaching Boaz. Boaz did all the heavy lifting here, he accomplished her redemption when she could not. Her redeemer wasn't willing to redeem, but Boaz was and made sure that it happened.
And so it is with us, we humbly approach the Lord in faith in our time of need and he acts on our behalf. The law that we hoped could redeem us could not, but Jesus made sure that we were redeemed. He, like Boaz, did the heavy lifting, we did nothing.
