The Old Testament book of Ruth is a story of friendship, love, loyalty and redemption. Ruth experienced the gift of redemption from her mother-in-law Naomi, her kinsman Boaz and God. We too receive redemption by God through Christ when we understand (1) our need; (2) our inability to redeem ourselves; and (3) that our redemption must come from outside of ourselves.
We have a saying "Good things come in little packages." This is certainly true when it comes to the Bible. There are short books of the Bible that we may never heard preached, know very little about and think they are insignificant. But they pack a powerful message for us in a little package.
