The answer is: Ruth

Ruth 1:16

In the book of Ruth, the profound declaration, "thy God shall be my God," illustrates a deeply pivotal moment in the narrative. This verse comes about when Ruth, a Moabite widow, passionately chooses to follow her mother-in-law Naomi back to Israel after the death of their husbands. Her statement is filled with commitment and loyalty, marking a critical turn in the text where she embraces not just Naomi, but also Naomi's faith and culture.

Ruth's allegiance to Naomi can be viewed as a remarkable act of love and commitment. Interestingly, it foreshadows and embodies themes of faith, redemption, and inclusion that echo throughout the Bible. In many ways, Ruth's story mirrors that of later biblical messages emphasizing God's outreach beyond cultural and ethnic boundaries. Did you know Ruth eventually became one of the great-grandmothers of King David? Talk about a power-packed family tree!

Literally, her name, "Ruth," means "friend" in Hebrew, and the bond between her and Naomi is one of friendship and resilience. Returning with her, Ruth also exemplifies the embrace of new faiths and ideas, and her story serves as an early illustration of the values of acceptance and divine providence. The line marks a doorway through which we see how personal choice can shape one's identity and legacy, reflecting the journey of many seekers of truth through ages.
