"Miriam and Aaron spoke against Moses because of the Cushite woman whom he had married, for he had married a Cushite woman. And they said, "Has the LORD indeed spoken only through Moses? Has he not spoken through us also?"...When the cloud removed from over the tent, behold, Miriam was leprous, like snow. And Aaron turned toward Miriam, and behold, she was leprous. (Numbers 12:1-2,10)
One thing that is abundantly clear in the Scriptures is that God has created every race and deems every one important in his eyes. All of the nations, races, and ethnicities on earth are created to worship and manifest the full-orbed nature of the glory of God. They were made to deny every claim of prideful superiority, even superiority due to race, and find joy in a supremely valuable God. Subsequently, every joke or subltle claim to superiority that demeans this reality is sin and racist, and is equally as bad as the more blankly racist hatred that seems obvious today. Indeed, it is a sin which is just as damnable as adultery, murder, and idolatry.
To a large extent, racism is idolatry. After all, racism is as the dictionary says, "a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usually involving the idea that one's own race is superior and has the right to rule others." If one believes that they are superior to another, they are setting themselves up for worship and to be served, and not to worship and serve the only One who is worthy. Racist jokes are subtle, but they are nevertheless an affront to the Creator's handiwork and the reason why other races were made. They were made to worship God, not to be belittled.
In the text before us, Miriam and Aaron frowned upon Moses' selection of the Cushite woman because she was of a darker complexion. In addition they displayed their pride by wanting God to work and speak through them for self-serving reasons. What did the Lord do as a result? He smote her with leprosy. It is as if God was saying, "You like people to be white? I'll show you white!" And there it was, Miriam became as white as snow. This is serious business to God because it puffs man up, and does not produce the type of humility that sees God as supremely valuable.
As I have worked in the Southern United States I have become more sensitive to these matters. When working at UPS during a break I happened to follow along in a group conversation that was occuring around the smokeshack. It just so happened that an individual who was African-American walked in on the conversation and one of the people said, "What are you doing? This is a Caucasian meeting." And laughter ensued.
This kind of joking is not just limited to the South, either. Where I am from one is more likely to hear a joke about Somalis or Mexicans. So my point is not to say, "The South is to blame." My point is that even though these jokes are prevalent anywhere you go, we cannot escape the reason why these jokes are said. Why is the joke above, for example, funny to begin with? It is funny because of the irony: "We are all white, and here is this guy who is black who just came in. And because of my prideful nature I am going to point out to the whole group that you are black and we are all white. Therefore, you as an individual should not be given any credance because of your skin color." And yet, we laugh.
What is the reason that the nations were created, at the end of the day? In part, it was for the culmination of redemptive history. Every nation and race was created to worship Christ alone and thereby show that there is no basis in man worthy of worship, including skin color. All are sinners and worthy of only death, BUT Christ has come to make us free. He has come "once for all, the righteous for the unrighteous, to bring us to God" (1 Peter 3:18). All ethnicities were created to love and serve and deem Jesus to be superior and all-glorious. They were created to find joy not in others finding them praiseworthy because of their background, but instead to find joy in making much of Christ. "And they sang a new song, saying, 'Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth'" (Revelation 5:9-10).
So humble yourself, whether you are from the South, North, East, or West. We are not better because we are white, black, Asian, or Mexican. We are all sinners who desperately need Christ. And we need to see every opportunity with other races as an opportunity to display the glorious nature of the One who will call out for himself a people from every tribe and tongue and people and nation to glorify him. Making light of race makes light of God and the reason why the races were made in the first place.
