Ruth 4

"So Boaz took Ruth into his home, and she became his wife. When he slept with her, the LORD enabled her to become pregnant, and she gave birth to a son. Then the women of the town said to Naomi, 'Praise the LORD, who has now provided a redeemer for your family! May this child be famous in Israel. May he restore your youth and care for you in your old age. For he is the son of your daughter-in-law who loves you and has been better to you than seven sons!'
Naomi took the baby and cuddled him to her breast. And she cared for him as if he were her own. The neighbor women said, 'Now at last Naomi has a son again!' And they named him Obed. He became the father of Jesse and the grandfather of David." v13-17
To some, the book of Ruth may be just a nice story about a girl who was fortunate. But in reality, the events recorded in Ruth were part of Gods preparation for the births of David and of Jesus, the promised Messiah. Just as Ruth was unaware of this larger purpose in her life, we will not know the full purpose and importance of our lives until we are able to look back from the perspective of eternity. We must make our choices with God's eternal value in mind. Taking moral shortcuts and living for short-range pleasures are not good ways to move ahead. Because of Ruth's faithful obedience, her life and legacy were significant even though she couldn't see all the results. Live in faithfulness to God, knowing that the significance of life will extend beyond your lifetime. The rewards will outweigh any sacrifice you may have made.
