You may remember a few chapters back when Ruth worked hard pacing the fields and following the reaper’s footsteps. Now, as she has become one with the owner, that land becomes her inheritance.
As Hank mentioned there are many similarities to Boaz as Ruth’s Kinsman-Redeemer and Jesus as ours. Just as Ruth became one with her husband and no longer worked the fields, when we become one with Christ, we no longer work for our redemption. We are redeemed and united with Christ, resurrected with Him in the Spirit while bearing fruit for our Lord.
There is foreshadowing here as well since Ruth was a Gentile. This story illustrates the Gospel’s implications on all every tribe, tongue, and race. Jesus has come to redeem all His faithful followers!
