The Bible does not oppose or forbid interracial marriages but sees them as a positive good for the glory of Christ.
John PiperThe offspring of the woman, Jesus Christ, came into the world to save women who have dethroned God, taken His place, defined personhood as tissue, and willed the death of their own child. It can't be reversed, but it can be forgiven. That is why Christ died.
John PiperThe deepest need that you and I have in weakness and adversity is not quick relief, but the well-grounded confidence that what is happening to us is part of the greatest purpose of God in the universe - the glorification of the grace and power of his Son - the grace and power that bore Him to the cross and kept him there until the work of love was done.
