How does Ruth's story illustrate grace?

Ruth, a Moabite woman, experienced profound grace as she was integrated into the lineage of God’s chosen people. Her confession that 'Thy God shall be my God' reflects a significant spiritual transition. This act of faith and commitment allowed her to partake in the blessings of God’s covenant community, despite the cultural and historical enmities between Moabites and Israelites. Her story underscores the Reformed tenet that God's grace is available to all, irrespective of background, revealing the universality of His redemptive plan, which culminates in the Gospel.
