Race is a gospel issue.
Race is a gospel issue because our world, though one in Adam, is divided by ethnicity, nationality, tribal distinctions, and social classes. We are one people in our common parentage, but we are not one in the way we treat each other. We are not one when we plunder one another, fight one another, oppress one another, and destroy one another because of racial differences. Someone might say at this point, "Yes but this is a matter of simply recognizing the image of God in each other. That's not a gospel issue."
But what gives you the eyes to see and ears to hear the image of God in your fellow man clearly and truly other than the gospel? Christ is the new and better Adam, and only by seeing his life can we see and understand true life and all the lives around us. Common grace is given by God, to be sure, but until our eyes are opened by the power of the Holy Spirit and the light of the gospel we only see one another through a glass darkly. Sin clouds our minds and our thoughts about one another.
Race is a gospel issue because only by the light of the gospel can we truly understand our diversity and unity in Adam and, for those who are believers, in Christ.
Race is a gospel issue because the Old Testament says it is. God makes a race out of Abraham and Israel, his chosen people. Israel does not exist as an ethnic group or nationality until God makes them! God has chosen to redeem the world through one particular ethnicity, indeed through one man from that particular ethnicity, and through that one man to bless the nations. God, through one race, draws all races to himself. Every tribe, tongue, and nation. The good news of the gospel is through one race and for all races, so that at the coming of our Lord Jesus every knee from every race should bow and every tongue from every ethnicity should confess that Christ is King.
Race is a gospel issue because the New Testament says it is. Jesus sends his disciples out to proclaim the good news of his death and resurrection to all nations, to the ends of the earth. The gospel is for all people, which in the New Testament would be read as saying it is for all kinds of people, that is, all races, ethnicities, classes, etc. The book of Acts narrates this in dramatic form, with the gospel going first to the Jew and then to the Gentile. Romans, Galatians, and Ephesians all explain the gospel so that their readers will understand how both Jew and Gentile can be part of the one people of God.
Paul's majestic explanation of the height and breadth and length and depth of Christ's atoning work is set in the context of racial unity in the church! Galatians tells us that male, female, barbarian, Scythian, slave, and free are one in Christ – these are socio-economic and racial distinctions. The gospel of Jesus Christ speaks to the unity of a once disparate group of people. Ephesians 2:15 tells us the same – we are one new man in Christ Jesus. That's one new man made from different racial groups. The gospel speaks to race.
In fact, if race wasn't affected by the gospel, most of us [Gentiles] would still be without God and without hope in the world (Eph. 2:12). Philemon's uniqueness in the canon is, in part, the fact that it applies the gospel specifically to social and perhaps racial divides between believers. 1 Peter 2:9-10, again speaking to us Gentiles, tells us that we who were once not a people are now his people. Why? Because the gospel transcends and subverts racial divides.
