During the darkest days of apartheid in South Africa, when the government banned all public protest, Archbishop Desmond Tutu held a church service at St George’s Cathedral. Hundreds of police gathered outside, then entered the Cathedral as Tutu was preaching, taking out notebooks to record his words. But Tutu refused to be intimidated. He preached against the evils of apartheid, declaring that it could not endure. Then he addressed the police directly. ‘You are very powerful,’ he said. ‘But you are not gods and I serve a God who cannot be mocked. So, since you’ve already lost, I invite you today to come and join the winning side.’ With that the congregation erupted in dance and song and the police withdrew, overcome by Tutu’s confidence that God and goodness would eventually triumph.
