Sam cooke meant that one day, even through all the racism that he had to live with, all of it will end and everybody, no matter what color, race religion, or whatever; will get along without discrimination.
So if you really are racist you need to rethink where you are in life. Where I live black people, part of the many races that I am, are racist against white people. So I get attacked everyday because they say that my behavior is 'white'. The two major people who help me get through this are my brother and mother. My brother is half white but looks white and my mother is over one fourth white. I grew up without a father and eventually I realized that it's not the color of your skin or where your family's from or even where you go to church at, it's the content of your character and that is why I have few friends where I live. Anybody with me on that?
