I would really appreciate it if you could answer my question: Is it wrong to marry a person from a different race group?
In the Bible the concept of race doesn't exist. There are nationalities, but God states that all of mankind is one race. That is because all of us descend from the same couple: Adam and Eve. "He has made from one blood every nation of men to dwell on all the face of the earth" (Acts 17:26). The concept of race is an artificial division of mankind based on external variations.
If you want to marry a person who looks different than you do, there is nothing wrong with it.
