As a member of a despised people, Ruth was defenseless in the nation of Israel. But Boaz, a picture of Jesus Christ, had heard how the Moabitess showed kindness to Naomi, so he offered to protect her as a daughter. Later, he came to love her as a wife. Like God, Boaz was unprejudiced and gladly welcomed a foreigner into his family.
Because God is unprejudiced, he welcomes anyone of any race into his family (see Romans 2:11). He doesn’t care where you’re from, the color of your skin or what name you bear. And that same color-blind impartiality is what he expects his children to show others.
