Propitiation presupposes the wrath of God. Right here many modern thinkers would stop, arguing that the term should not be used. “We can understand,” such a person might say, “how the idea of propitiation would be appropriate in paganism where God was assumed to be capricious, easily offended and therefore often angry. But this is not the biblical picture of God. According to the Christian revelation, God is not angry. Rather, he is gracious and loving. Moreover, it is not God who is separated from us because of sin, but rather we who are separated from God.” Those who have argued this way have either rejected the idea of propitiation entirely, considering its presence in the Bible to be merely a carry-over from paganism, or they have interpreted the basic Greek word for propitiation to mean, not Christ’s propitiation of the wrath of God, but rather the covering over or expiation of our guilt by his sacrifice.

Second, although the word “propitiation” is used in biblical writings, it is not used in precisely the same way it is used in pagan writings. In pagan rituals, sacrifice was the means by which man placated an offended deity. But in Christianity, it is never the man who takes the initiative or makes the sacrifice, but God himself who out of his great love for the sinner provides the way by which his own wrath against sin may be averted. Moreover, he is himself the way–in Jesus. This is the true explanation of why God is never the explicit object of the propitiation in the biblical writings. He is not the object because he is, even more importantly, the subject. In other words, God himself placates his wrath against sin so that his love may go out to embrace and fully save 
The second great term for God’s work of salvation is redemption. Redemption speaks of what Jesus Christ did for us in salvation and of what it cost him to do it. It also occurs in Romans 3:23-26, and in many other places.

The Greek word translated as “redeem,” “Redeemer” or “redemption” in our Bibles has to do with loosing someone’s bonds so that, for example, a prisoner becomes free. At times it was used of procuring the release of a prisoner by means of a ransom. Spiritually, the idea is that, though we have fallen into desperate slavery through sin and are held as by a cruel tyrant, Christ has nevertheless purchased our freedom from sin by his own blood. He paid the price to free us.

We have what is perhaps the greatest biblical illustration of redemption in the story of Hosea. Hosea was a minor prophet whose marriage was unfortunate from a human viewpoint, for the woman proved unfaithful to him. But it was a special marriage from the viewpoint of God. God had told Hosea that the marriage would work out in this fashion. Nevertheless, he was to go through with it in order to provide an illustration of how God loves his people, even when they prove unfaithful by committing spiritual adultery with the world and its gods. The marriage was to be a pageant in which Hosea was to play the part of God and his wife would play the part of unfaithful Israel.

The climax comes at the point at which Gomer fell into slavery, probably because of debt. Hosea was told to buy her back as a demonstration of the way by which the faithful God loves and saves his people. Slaves were always sold naked in the ancient world, and this would have been true of Gomer as she was put up on the auction block in the city of Samaria. She apparently was a beautiful woman. So when the bidding started the offers were high, as the men of the city bid for the body of the female slave.

The bidding was competitive. But as the low bidders dropped out, someone added, “Fifteen pieces of silver and a bushel of barley.”

Paul’s own conversion is an illustration of these points. He was not a hedonist; far from it. He was better than that, having effected in his life a combination of the second and third types of men he described in the opening chapters of Romans. He was religious and moral, and he trusted for his salvation to what he could achieve in these areas. He tells about it in Philippians 3:4-8: “If anyone else thinks he has reasons to put confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for legalistic righteousness, faultless. But whatever was to my profit I now consider loss for the sake of Christ.”

What Paul is saying is that in the days before he met Christ, he had something like a balance sheet in his life. It had assets and liabilities, and he thought that being saved consisted in having more in the column of assets than in the column of liabilities. Moreover, he thought there were considerable assets, some inherited and some earned. Among the inherited assets was the fact that Paul had been born into a Jewish family and had been circumcised according to Jewish law on the eighth day of life. He was a pure-blooded Jew, born of Jewish parents (“a Hebrew of Hebrews”). He was also an Israelite, that is, a member of God’s covenant people. Moreover, he was of the loyal tribe of Benjamin. Then, too, Paul had advantages that he had won for himself. In regard to the law, he was a Pharisee, the most faithful of all Jewish sects in adherence to the law. Moreover, he had been a zealous Pharisee, which he had proved by his persecution of the infant church.
