Question

How does this language effectively appeal to the audience emotions and get edwards message across?

Answer 1

Since Edward has used a descriptive language to draw the attention of audience it is always a way which fuels curiosity and desperation and same happened with the audience of Edward, they got desperate and confused.
Edward has painted the image of God as a ruthless guard who at any time is ready to punish and humanity a bunch of creature whom God does not love as creature but He has the scale of punishment only.
