Ruth chapter 4
Boaz redeemed Ruth according to custom, in the presence of witnesses. His redemption is a type of Jesus Christ redeeming us from sin. According to the law the redeemer had to be:
1. A near kinsman (Deuteronomy 25).
2. Willing to redeem (John 10:18;No one can take my life from me. I sacrifice it voluntarily. For I have the authority to lay it down when I want to and also to take it up again. For this is what my Father has commanded.”
Isaiah 53:7; He was oppressed and treated harshly,yet he never said a word.
He was led like a lamb to the slaughter.And as a sheep is silent before the shearers,he did not open his mouth.
Galatians 2:20;My old self has been crucified with Christ. It is no longer I who live, but Christ lives in me. So I live in this earthly body by trusting in the Son of God, who loved me and gave himself for me.).
3. Have the ability to redeem (John 10:11-18).
4. Be free himself(be a free man, not under sin bondage), just as Jesus was free from sin.
5. Have the price of redemption, which was the blood line. We are redeemed by the blood of Jesus (I Peter 1:18-19;For you know that God paid a ransom to save you from the empty life you inherited from your ancestors. And it was not paid with mere gold or silver, which lose their value. 19It was the precious blood of Christ, the sinless, spotless Lamb of God.
Leviticus 17:11; for the life of the body is in its blood. I have given you the blood on the altar to purify you, making you right with the Lord.
Hebrews 10:4;For it is not possible for the blood of bulls and goats to take away sins.).
Just as Boaz met these requirements in the natural redemption of Ruth, Jesus met them in the spiritual redemption of man.
