"I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character."
Personally, I think it's pretty cool that there's a federal holiday honoring a preacher!
When you think about it, Dr. King's advocacy for civil rights was rooted in his faith. The quote I cited above is pretty much aligned with the biblical verse of Acts 10:34 where Peter declared that "God is no respecter of persons." That is, He holds no human in any higher regard than another. You can also look at Mark 12:31, which states that you shall "‘love your neighbor as yourself.’ There is no other commandment greater than these.” Again, there's no qualifier on if someone looks different from us.
I can say that I am honored to live in a country which dedicates a single day to a man who steadfastly and unabashedly proclaimed his faith in an effort to advance his cause. While there may be some who claim vast racial inequality still exists, there can be little debate in how Dr. King's bringing the issue to the forefront in the '60s definitely bridged the divide.
