Final answer:
The statement is True, as the marriage of Boaz and Ruth plays a pivotal role in the biblical lineage that fulfills God's promise to Abraham to bless all nations through his descendants.
Step-by-step explanation:
The statement that God's promise to Abraham begins to come to fruition through Boaz and Ruth is True. According to the Hebrew Bible, God made a Covenant with Abraham, ensuring that his descendants would be numerous and would inherit a land of prosperity. This is significant in Jewish faith as it marks the beginning of the Hebrews as a distinct group. In the book of Ruth in the Bible, Boaz, a relative of Abraham's family, marries Ruth, a Moabite woman. Ruth's loyalty to the God of Israel and her marriage to Boaz ties her to the lineage leading to King David and, according to Christian belief, to Jesus Christ. Thus, the union of Boaz and Ruth is seen as a key step in the fulfillment of the promise that Abraham's descendants would be a blessing to all nations.
