“When Moses walked into the courts of Pharaoh and thundered forth with the call to "Let my people go," he introduced into history the concept of a God who was concerned about the freedom and dignity of all his children and who was willing to turn heaven and earth that freedom might be a realty. Throughout the history of Israel as recorded in the Old Testament, we see God active in the affairs of men, struggling relentlessly against the forces of evil that beset them and seeking to mold a people who will serve as his children, as partners in the building of His kingdom here on earth. The God of our fathers is a God of revolution. He will not be content with anything less than perfection in His children and in their society. It is this strong biblical tradition which has been the foundation of the freedom struggle for the past three centuries.”

Context: When Moses walked into the courts of Pharaoh and thundered forth with the call to "Let my people go," he introduced into history the concept of a God who was concerned about the freedom and dignity of all his children and who was willing to turn heaven and earth that freedom might be a realty. Throughout the history of Israel as recorded in the Old Testament, we see God active in the affairs of men, struggling relentlessly against the forces of evil that beset them and seeking to mold a people who will serve as his children, as partners in the building of His kingdom here on earth. The God of our fathers is a God of revolution. He will not be content with anything less than perfection in His children and in their society. It is this strong biblical tradition which has been the foundation of the freedom struggle for the past three centuries. As far as back as the early days of slavery black men heard the story of Mosees and learned of this great God who would lead his people to freedom, and so they sang, "Go Down Moses." They sang of a "Balm in Gilead" that would "heal the sin-sick soul" and "make the wounded whole." They sand of Ezekial's dry bones and prophesied the day when the dry bones of the valleys of our land would rise up and become men and stand tall for freedom and dignity.
