According to the story of creation narrated in the Bible, all human beings are created in the image of God. As God’s image-bearers, all people need equal freedom, dignity, and justice. However, this core value of humanity is being neglected, and people are mistreating, exploiting, and killing others based on their ethnic origins. A country with a multiethnic society faces the worst challenge in this regard. This essay offers biblical and extrabiblical evidence for addressing the tensions between ethnicity and humanity in the image of God from a systematic theological standpoint, whereby attention is called to a harmonious and peaceful relationship between people of different ethnic heritages.
