Crusades are wonderful things. Slavery was eliminated in the British Empire in the early 19th century when the English Christian churches fought against it. Child labour was brought to an end because a writer like Charles Dickens made an issue of it.
Tommy Douglas was the first politician to introduce public health insurance to Canada.
University students in the U.S. organized against the Veitnam war and helped bring it to an end.
At the Aids Conference in Toronto, Bill Gates dedicated half a billion dollars to manage and lessen this dreaded disease.
Most of us may not be in a postion to do what Bill Gates did or to directly influence evils like "The Middle East Wars", "Global Warming", and the "World Trade Barriers" that continue poverty in Third World countries.
However, we all can become prayer warriors and link up with other crusading spirits who want to lessen those destructive conditions that can bring us all down. It's not total evil eradication. It's just making the world a better place to live in for ourselves and our children.
