And He said to them, “Go into all the world and preach the gospel to every creature.” Mark 16:15
Our modern English words ethnic and ethnicity come from the Greek word ethnos which meant people groups. When Jesus told His disciples to go and make disciples of “all the nations” (Matthew 28:19–ethne), he wasn’t referring to political nations. He was referring to all the world’s peoples—the Gentiles of the world. And in Mark’s version of the Great Commission—“preach the gospel to every creature”—the same thing is meant: preach to all creation (Greek ktisis—creature or creation).
In other words, Jesus’ Gospel was not just for Jews. Since the days of Isaiah the prophet, the Servant of the Lord was destined to come as a “light to the Gentiles” (Isaiah 42:6; 49:6; Acts 13:47). It has never been easier to take the Gospel to every person, every ethnicity, every creature, than it is today. In your neighborhood and workplace, you likely have people representing a diversity of ethnicities from around the world. Can you share the Gospel with them?
To be a missionary today, you only have to leave your front door. The world has come to us; we must offer Jesus to them.
Every Christian is either a missionary or an impostor. Charles H. Spurgeon
