Yes, St Francis of Assisi was right when he said 800 years ago: “Preach the gospel at all times, if necessary use words.” But not fully right. Romans 10:14-15 says "How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can anyone preach unless they are sent?”
We have to be the sent ones that say something. So let's all take a gulp, and say some gospel!
