Using a shofar, I have combined elements of shofar blowing, testimony, and evangelical methods including apologetics into an approach I call “Shofar Evangelism”.
All I know is God told me to go out in public and sound the shofar, so I do. The “shofar evangelism developed from conversations I found myself having as a result of sounding the shofar around other people (such as in parks)
There is a team of like minded people called Watchmen.
There is an entire menu of shofar related pages above with text and videos of why and how I do it.
