Redemption always costs something. It's not clean or easy. And for Boaz it looks like legal action. He has weighed the responsibility and is ready to redeem if the nearer kinsman redeemer refuses. This unknown redeemer, concerned with earthly inheritance, isn't willing to pay the cost. By grace, we have a Redeemer in Jesus Christ, who gave up His inheritance in heaven to come pay the cost of redemption for us with His own life.
