Here are common concerns that Christian couples that are interracial:

1) how about the children?

Whenever some body asks me this, I do believe of the quote by Lee Chanult from his book, Mixed Messages:

“What white people are saying with that statement is they think racial prejudice is awful, particularly when it affects young ones, and they sure are glad their young ones are white!”

Finally, it is the duty of loving Christian parents to teach their children that their identity is mainly that of Christ; every other label is additional.
