In Numbers 15:1-16, God is preparing the Israelites for a new season, telling them how they should offer their sacrifices when they get to the Promised Land. He tells them that if a foreigner lives among them, "they must do exactly as you do. The community is to have the same rules for you and for the foreigner residing among you...You and the foreigner shall be the same before the Lord. The same laws and regulations will apply both to you and to the foreigner residing among you." (verses 14-16)
So for example, an Egyptian traveling with the Israelites could not say, "I don't need to follow these laws regarding worshiping only one God because I am from Egypt and in my culture we recognize and worship many gods." No. As long as you want to live among God's people, you're subject to the same rules as the rest of God's people. You don't get a "pass" because of your culture.
In a similar way, when it comes to Christ and His kingdom, all distinctions based on race, ethnicity, culture or background are removed. All of us are under sin, and all of us need Jesus to save us from our sin. This is great news. No matter what your background is, you can have a relationship with God, you can be forgiven of your sins, and you can be adopted into God's family -- all through Jesus Christ and His death on the cross. It doesn't matter if you're rich or poor, male or female, young or old, or what culture or country you come from. Through Christ all of us get access to the same benefits, the same acceptance, the same forgiveness, and the same love from God. In addition, through Christ, all of us regardless of our race, culture and background, get the same responsibilities to fulfill, the same commands to obey, and the same mission to complete (which is to win the world to Christ).
As Paul writes in Galatians 3:28, "there is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus", and in Colossians 3:11, "Here there is no Greek or Jew, circumcised or uncircumcised, barbarian, Scythian, slave or free, but Christ is all, and is in all."
So if God's people includes people from all sorts of backgrounds who have placed their faith in Christ, let me ask you: Do you hold any prejudices against people based on their race, culture or background, or based on their social or economic status? Do you refuse to associate with certain people simply because of their culture or social status? Just as God loved this entire world and all the people in it, and just as God accepted all of us in Christ regardless of our background, may we show the love of Christ to all people regardless of their background. All people are precious to God.
