Some people really need shit spelled out to them. This does a great job of doing that in a small package.

I doubt this sort of rhetoric will convince a modern audience. Reads like “Sinners in the Hands of an Angry God”.

It's not the rhetoric that should convince you, it's the logic. The rhetoric here is purely to liven it up.

Same could be said for SITHOAG. Yet, modern preachers have found far more success with other approaches.

Consider: if the tone of your writing will put off anyone who disagrees with you, what’s the value in “livening it up”? Again, it’s preaching to the choir.
